I think more information is needed on all sides. I'm feeling like this is a bit us vs them, which is what I think we all want to get away from.
I would like to suggest three things.
1. create a list of questions and try to stick to them so this doesn't turn into a rehashing of the past, this is movement forward and providing solutions to problems.
2. start a thread asking the forum community what they would like to see in a chatroom (interface (web/irc/?) topics, issues, etc. Have a set time limit to the forum, ie this will run for 1 week and will be used as reference point to improve service to both communities (forum&chat)
3. schedule a chat in channel during the time period mentioned above, have Morrus, MM, Xmanii, channel ops, Bynw and anyone else I'm missing there, and get the same input from the chat community.
I think that would provide a starting point for making decisions that would benefit all of the community.
