Post-Registration Redirect

The process I'm trying to achieve is pretty simple. When a new user registers (I'm using BuddyPress) they are currently shown an activation page (though the URL doesn't appear to change). I'm trying to figure out a way to send new registrations to a specific page (which shows the membership options on the site) immediately.

I tried the WPMU plugin for redirect but it's not quite what I need, and a couple other plugins either don't work or aren't compatible.

Any ideas?
