A common request we get is adding some kind of chat system to our forum. The Shoutbox plugin covers part of that wish, but obviously not all of it.
An official chat system addon for the board exists, but using it would require us to change our current licence to a regular one with less advantages (free upgrades forever) and pay an additional $80 per year. For a technology that's not really suited for real-time chat anyway. It may be an option in the future, but for now we've decided to go a different route.
We've created a permanent IRC channel for Revora called #revora at the freenode IRC network. To join us, download an IRC client, connect to chat.freenode.net and then /join #revora. If you don't know how to do that, you'll find lots of IRC tutorials with your favourite search engine (I'm an IRC beginner myself). The advantage of IRC is that it's fast, simple and has been successfully used for decades.
The channel is still very empty at the moment as only Starkku and me have joined it, but I bet if we can get a few people online, there will be a nice casual discussion. IRC also supports private chats if you need that.
Admins can contact me to get permanent operator status in the channel.
