Changes to Groundspeak and are posted in their forums under Announcements at

I stay out of the forums when possible, but this one is worth not only knowing about but subscribing to.

You will, if subscribed, only get a few notices of new posts, because things don't change that frequently, but when a change occurs or is about to, you should know.

In this case those of you considering changing your username must do it before May 15 or live with it forever!
