• Starting Up…
  If you've just started I2P, the Active: numbers on the left should start to grow over the next few minutes and you'll see a "shared clients" local destination listed at the bottom of the sidepanel on the left (if not, see below). The first time you start I2P it may take a few minutes to bootstrap you into the network and find additional peers to optimize your integration, so please be patient. Once green stars are indicated next to your local destinations, there are a range of things to do with I2P including:

Services on I2P

• Anonymous File Transfer
  I2PSnark is integrated into I2P, providing anonymous, encrypted bittorrent. Also, Sponge develops a bittorrent client called Robert written in Python. There is also a port of eMule to I2P called iMule [Urgently needs developers!], a hookup into the gnutella network in the shape of IPhex, filedumps, webuploads et al.
• Anonymous E-mail
  Postman's I2P-based mail system can be accessed either via I2P's built-in webmail (aka susimail) or using any mail client that supports smtp and pop3. Accounts can send and receive mail from the normal internet. For an account, visit hq.postman.i2p. Additionally, I2P-Bote is a new serverless, end-to-end encrypted e-mail system (with web interface), installable as a plugin.
• Anonymous Chat
  Start your IRC client (eg. chatzilla) and connect to the server at 127.0.0.1 port 6668. Your local I2P IRC proxy on localhost:6668 will direct you to one of two IRC servers hosted on I2P by Postman and Badger, but neither you nor they know where the other is, and your mom, ISP or government is unable to intercept your conversation! Once you're there, #i2p, #i2p-help, #i2p-chat and #i2p-dev are just a few of the available channels you may wish to /join. There's also a I2P based instant messenger for unmonitorable, uncensorable, anonymous chat.
• Forums & Blogging
  Syndie is a distributed forum and blogging plaform for I2P [Urgently needs developers!]. There's also an I2P plugin port of the Java-based pebble blogging platform ported to I2P by zzz, available on i2plugins.i2p. And of course all normal blogging, forum and cms software will run over I2P, though you're advised to take extra precautions with security when setting up and keep all associated software (eg. Php, MySql, Python, Apache etc) up to date and locked down!
• Plugins for I2P
  Extend the usefulness of I2P by installing plugins… you can browse the plugins and related info on i2plugins.i2p. If you're a developer, a complete language agnostic framework for writing your own plugins is provided with documentation; I2P plugins can be coded in any language. Blogging, chatting, filesharing and other plugins have already been written or ported and await your installation!
• I2P Darknet & Public Web browsing
  On I2P you can host anonymous websites (aka eepsites) and other services (eg. ssh over I2p, your own irc server etc), and you can also access the normal web anonymously via I2P. Configure your browser to use the HTTP proxy I2P provides at 127.0.0.1 port 4444, then browse to an eepsite or a normal http:// address. Some useful resources are listed below:

Anonymous Encrypted Webserving on I2P

• Ready to roll!
  I2P comes built-in with a ready-to-go webserver for hosting your own anonymous website (eepsite) on the I2P darknet: a Jetty instance listening on http://127.0.0.1:7658/. To host your own content simply place your files in the eepsite/docroot/ directory (or place any standard JSP/Servlet .war files under eepsite/webapps, or standard CGI script under eepsite/cgi-bin) and they'll show up. You can also run any alternative webserver platform over I2P and replace the built-in server, or run it on another tunnel.
• Start your tunnel
  After starting up your pre-configured I2P Webserver tunnel, your eepsite will be visible (but not discoverable) to others. Detailed instructions for starting your eepsite, registering an .i2p domain and promoting your site to others are accessible via your own I2P websever on http://127.0.0.1:7658/help/.

Troubleshooting & Further Assistance

• Be patient!
  I2P may be slow to start the first time as it searches for peers. If, after 30 minutes, your Active: connected/recent count has less than 10 connected peers, you should open I2P's port on your modem, router and/or firewall(s) for better connectivity. More information on how to go about port forwarding can be found at portforward.com, in addition to our forums and irc channels listed elsewhere.
• Check your proxy setttings
  If you cannot see any eepsites at all (even www.i2p2.i2p), be sure your browser proxy is set to access http traffic (not https, not socks) via 127.0.0.1 port 4444.
• Getting support online
  You may also want to review the information on the I2P website, post up messages to the I2P discussion forum, or swing by #i2p-help, #i2p or #i2p-chat on I2P's internal IRC network (irc.postman.i2p or irc.freshcoffee.i2p). These channels are also available outside of I2P's encrypted, anonymous servers via Freenode IRC.
• Reporting Bugs
  If you'd like to report a bug, please file a ticket on trac.i2p2.i2p. For developer related discussions, please visit zzz's developer forums or come and visit the developer channel on I2P's IRC network. Developers can browse source at zzz's mtn repository viewer or Sponge's version.
