You can find an introduction to Internet Relay Chat and more at IRChelp.org.
Like most IRC channels, ours is not especially "on-topic," but it's a great place to get advice about using your HCoop account. Please join and "idle" there if you can to help build momentum and answer other members' questions!
Our volunteer admins don't treat IRC as an official support method, because it is way too hard to organize handling of support requests that come over such an unstructured medium. This means that you're free to ask questions or make requests that can only be answered/fulfilled by admins, but that they won't feel obligated to reply. Open a support ticket on the portal for such issues.
