Can you try again. I did not notice earlier that 5 of your posts were today, right up to 5:56 PM CT.
You 10th post ( to make the cut ) was at 5:07 PM CT, which the change from member to be able to post in that section ( and PM other members with this level also ) only happens once per hour, so it could have been 6:00 PM CT ( or slightly after ) before your could do the classified or PM ( which I PM'd you earlier, so I know that part was working at 8:15 PM CT ).
Give it a go, and let us know if you still have problems
Just the way the software "promotes" users from one level to another.
