Sorry about not getting back to you - I've got my e-mail spam filter set quite high as I get lots of spam e-mails through that account and I think it may have been gobbled up!
I'm not able to bend the rules about the for sale section unfortunately (which is activated automatically after 10 days + 50 posts), as the for sale section is run without any guarantee or warranty from this site. The minimum requirements are essentially the only level of protection we can offer to users, which should stop most problems that could occur from rogue traders. I hope you don't take this personally, but as it's the only level of protection we can offer it wouldn't be fair for me to change the rules as and when
I'm aware that makes me sound like a jobsworth, but as the service is only for active site members, the 50 post barrier isn't too high and you'll reach it in no time
