I got it, but the clan interface is weird. I have you as a bnet friend, but I still cannot invite to clan. If you search "unionvgf" you should be able to request an invite. The system is really weird, but I can't figure out how to invite someone. I tried on both PS and Xbox. Maybe I'll install the PC version and see.
I'm sure there's some button press I'm missing somewhere. I googled, and there seems to be no way to do it unless we're standing next to each other in the game. I think if you search the clan and request, that works. Anyway, everyone's welcome, I just can't figure out this awful interface.
