IRCloggy helps projects communicate by keeping records of their discussions on IRC. The logs can be read on the web frontent or searched for some keywords.
Many projects asked to log their IRC channels. You probably already met the bot called ilogger2 on some channel. The logs are updated in realtime. Since 2005, the website at colabti.org provides logs of IRC channels with IRCloggy. Previously, the project was known as IRC Logger 2.
