There isn't such a place, and the XOOPS.org team will probably not create one either. This because we would like as many people to benefit as possible from what every member of the community asks and answers, hacks and codes, writes and designs. The xoops.org websites are the central spot where all this knowledge is gathered, and archived. We're currently working with many people from the community to organise all this knowlegde, and adding yet another channel to that isn't going to help. Besides, the forums have a high enough speed to support many of the questions asked, the speed benefit of IRC or a chat module isn't really that big a bonus.
