Thats a great plugin, I have it installed. Its sends a invitation, but it would be great if it would auto enroll them. It would also be great if it would auto add a friend (like Tom on MySpace).
Talk to @DJPaul and see if he will add a forced join option then. I’m not sure why you’d want to do that though. Invites mean they have something in their inbox when they join and makes it a little more personal (IMHO).
I’ve been considering the same thing. In my research here’s the list of plugins I needed to still evaluate. Not a perfect plugin I think for this, but one of these plugins should be able to easily be modified to do what you want if you know a little PHP and WP/BP. Otherwise, I’m planning to dive into it myself over the next couple months. I hope these links help:

I also had the welcome pack on my list since it does make sense to have this part of it also.
