At the present minute the launch team are still porting across the forums so your patience is appreciated. In the mean time if you are looking for a clan why not enter that in your sig so recruiters may contact you?
I have seen alot of clan recruitment threads in the
Playdates and Community Forum that don't seem to be getting locked so I guess there is the place to post until they create an actual Clan Discussion and Recruitment Forum.
Or you could just put a link to your clan site in your signature as was suggested above.
