I've heard of the group in general but I don't know anything about their reputation nor know anyone personally who's belonged to it. They have managed to stay around for a while but that doesn't necessarily imply they're a large group. In my experience, most groups fall by the wayside and of those that manage to hang on it's due in large part to a smallish determined core keeping things together.
If it sounds interesting to you, no reason not to explore further. As I said, I've not heard anything good or bad about them. Personally, I'm not big on "we gather every __day", smacks too much of monotheism. But I also can appreciate that some people may resort to that approach since we're not in a polytheistic society and like-minded practitioners are scattered. YMMV.
