It was reported to me that registration was broken in the forums.  I checked and sure enough.  I chased this down to some mistakes I made in upgrading to 3.2.2, I did not remove all the incompatible themes and extensions first.

     I have corrected this but the downside is all the non-default themes, extensions, and language packs are gone until I get around to installing new versions compatible with 3.2.2 however, registration now works again.
