I would like to suggest that there be chat rooms added to the site. It is difficult to carry on a conversation when each post has to be approved. Depending on the forum and the time of day, an approval can be delayed as long as a day for some responses, while other responses are approved seemingly instantaneously. Sometimes, by the time a reply is posted, the conversation has turned to something else and the reply is no longer pertinent or even relevant.

And, what's up with the signatures? Still can't change them! 

 A fix is currently being implemented for the signatures.

And yes, we are discussing chat rooms as one of our enhancements for a later phase.
