While I realize this is an ENFP forum, I have been registered to this forum for months and suddenly find that I am not 'authorized' to post a message on specific threads?  This is peculiar in it's own right, and seems both trivial and capricious, however, I can accept that much in so far as internet forums are concerned, however given a fairly scrupulous browse through the forum rules and I can't derive even a reason for this set of circumstances?  

Really now, I can deal with rules, but what is the logic in this?

*scratches head*

which threads were they that you tried to post in? I agree that that is weird, but it sounds much more likely a glitch (at the moment, I don't think anyone is "authorized" to upload pictures to their profile either) than it does something saul put in place on purpose.
