What are the different levels of membership? I noticed I am listed as a junior member while others are "members". Just curious how this works. Thanks.

Make a few more posts.

There are officially four positions.

Junior member (1-5 posts)

Member (6+ posts)

Moderators

Administrators

The last two have specific duties and are not dependent on post count.

You will also see CUTs or Custom User Titles under names. These are often members who have somehow earned a customer title instead of "member."

Some are not members--stick around and you'll find out who these are.
