Our mantisbot lurks in the channel and keeps a log of all conversations. The archives can be found here. Should you want to go off the record, simply prefix your message with [nolog].
If you are looking for an IRC client, have a look at this wikipedia page, listing a number of options. Should you prefer to use a web client, feel free to use the widget below or connect using the Freenode webchat. Note that the Mibbit client has been disabled and can't be used on Freenode.
