Internet Relay Chat (IRC) is a chat service users can use to communicate with each other via text. It's designed for group communications but also allows one-on-one communication.
DreamHost has an unofficial IRC chat channel where customers and prospective customers alike can chat and support one another.
DreamHost's IRC channel
This channel is not an official means for support. The only guaranteed way to receive official support from DreamHost is via email, chat or call-back. View the Contacting DreamHost article for details.
Customers and prospective customers alike are welcome to join and help out one another, hang out, and get answers to questions not requiring a support ticket.
