It wasn't clear to me and I missed the addition on the top of each page. I'm just posting this out here for other members that may have missed this or didn't realize they had to go through another procedure. You can be a Forum Member without having MSTA Member Access. MSTA Member Access gives you certain access to places on the Forum such as the Members Only section.

Near the top of each page in a Notices bar, you can request the Forum Moderator to grant you MSTA Member Access by filling out an easy to complete form.
