That’s becuase you do not have enough posts. We put a post limit in place on purpose to stop spammers or people looking to try to rip others off and run from doing so. Spamming the site to get your post limit doesn’t work either.
Being you were registered prior to the old site, it doesn’t all crossover the same, hence your issue.
I'm having the same issue viewing the classifieds. Is there any way for accounts made before that rule to be grandfathered in? I'd rather keep lurking instead of making bs posts just to get my count up.
