Still wondering why I have these problems when I was treasurer and world council member now.
It's really weird, Kevv. Your permissions were OK, which means that you should be able to post anywhere, and I haven't heard of any SMF bug that would cause something like this. The only thing I can think of is a session cookie that's "stuck", somehow, but given that you've tried two browsers, I sort of doubt it.
I'll look into it some more and see what I can find.
