https://github.com/i2pchat/i2pchat has new important fixes

Note: this repo is being eventually migrated to https://github.com/i2pchat/i2pchat which should be considered as the main. This repo is deprecated.

• The communication goes «directly over i2p» from client to client, no server is required.[1] Note: The connections to the so-called «seedless» servers were removed from this project ; see : #40 . —hypn.

You need to enable SAM in your router on java i2p configclients page or i2pd's i2pd.conf [sam] section to make I2P Chat work over your I2P router.

When building this, make sure you do not define DEBUGLOGGING. If you do define it, the app will log debug info (which includes all chat messages) to configdir/DebugLog.txt if set DebugLogging to true in General group in the app's configuration. See main.cpp and form_settingsgui.cpp for more details on DEBUGLOGGING. All versions < 0.3.1 are affected by this and are less secure.

Now the development was resumed by Hypnosis-i2p and R4SAS, with a lot more folks as testers & bugs+issues reporters.

5 Jan, 2017: Original repo at http://git.repo.i2p/w/I2P-Messenger-QT.git was fully merged here.

Past. Original developer of this messenger went away.

Present. Hypnosis is continuing his work and the work of I2P folks (of Echelon, KYTV et al); the work is being done in a very low priority mode.
