The problem comes in when someone creates a record on PPA.com. It automatically creates a forum record for them. Because PPA.com is controlled by different software than the forum, folks don't get to see the old username requirement when they join us via ppa.com.

We could still change the username via the admin control panel, but it would break the connections between the website, the forum, the database system, and the customer service interface that we use.

For now tho, it offers users the convenience of a single login to access all areas of the site, and not having to register a second time to access the forums.
