Note:

BiglyBT can run a chatroom (named 'Anonymous') relying on I2P (if the I2P plugin is enabled)

↑ If Decentralized = yes, then the software or service does not rely on a main unique server.
↑ Chatrooms allows more than 2 people to 'talk' (by reading what others users are writing).
↑ If no, then the software or service rely totally on I2P.
↑ Are the messages stored encrypted on host/peers ?.
↑ It is possible to create so-called private communities where only invited members can post. This feature could be used as a chatroom.
↑ For Microsoft Windows .NET, URL: http://echelon.i2p/i2ptalk/
↑ The software IMule has a 'Messages' feature. You must know the I2P B32 destination of your friend running iMule in order to add him as a friend in iMUle (or he must be downloading a file from you, then you can add it with a right click).
↑ The service IRC2P is a IRC network running inside I2P. The software jIRCii is compatible with IRC2P.
↑ IRC2P relies on several IRC servers inter-connected.
↑ Multi OS, programmed in Java, URL: http://echelon.i2p/sic/
