Well whether Miranda NG supports ICQ group chats or not, the fact remains that they generally work, and I've been using them for years, on Miranda NG. The only thing that doesn't work is that the names of individual posters don't show. It would be nice to see full group chat support implemented. It's a feature I use all the time. Although I've never tried to start a group chat myself. My guess is that I can't do that either, but I certainly can participate in group chats, and do.
