If you're gonna hang out on this site with us, the first thing you need to do is to create a post on the site. You can put anything in the body of it at first, but make sure that the TITLE of the post is the Name that you want to go by on the site.
This post will be like your profile on the site (check out Ben's for an example), and I believe that only you will be able to edit it, but please keep the title the same so we can maintain the link.
This is sort of a MavGyver'd way to create profiles, and I hope it will work long term. We'll see. Thanks, -Mike
