a small issue I just found at the beta: when using "modal popup" the register link doesn't forward to jomsocial (which was selected) but routes to joomla default registration.
this doesn't happen for the register link in the popup itself (there it works correct) but at first appearance - see pic: http://screencast.com/t/53ZoHagLqvV3
keep up the great work,
Sorry about that. Yeah, it's a bug. Fortunately, there's a real easy fix. Check out this post with the minor change you'll need to make.
That, of course, will be in the next release as well.
If you have any other feedback about the module, just let me know. There's a lot of minor little changes that will be in the stable release later this month. In general though, this first pass at an overhaul has gone really well.
