I'm just putting this up as a warning.

When I was running my old RP forum, we had a little chatbox at the top of every page.  It was amazing and the small community spoke for HOURS on it.  However, our tiny site and our tiny chatbox overloaded my host's servers.  Used over 50% of the CPU, and we got taken down.

We're on a new host now, but that doesn't mean we're safe.  If the chatbox causes grief for the host it's going to get taken down again.

Enjoy it!
