If you would look to connect directly rather than via the web client, please join the #fluxbb channel on chat.freenode.net.
Please be aware that the IRC channel is English only. If you are looking for non-English support please see the international communities page
Note: Users on IRC are often idle and will only check for messages occasionally. If you don't get a response instantly then it can help to stay in the channel, someone will notice you eventually!
