Can some one help direct me how to post a new thread/question in "AOP Residential HVAC"?

That forum says I don't have permission (yet I have permission to post here).

I would have sent an message to the forum moderator "Dad", but apparently I don't have permission to do that either.

My question has to do with my 4.5 year old Lennox G61MPV 60c-111 with 14ACX and CX34-43C-6F-1 coil.
