According to Vik Olliver, there is now a RepRap IRC Channel on freenode.net...
"...where a lot of real-time assistance can be had, and the RepRap Project has applied for stewardship of it. If you've not used IRC before, the best way is probably a Firefox browser add-on called Chatzilla."
Use this data to connect to the channel using your favorite IRC client:
- Server: chat.freenode.net
- Channel: #reprap
