Hey,
I love how with using the MooTools Avatar Carousel set in groupJive mode it reads all the groupers on the GJ landing page but then filters out to only the actual group members when you are in a group page. Now that is freakin' cool!

So seems with a lot of sites, including this one some of the groups are lacking activity, so how about adding a thumbnailer to the top of the module that shows say the last visited dozen members with smaller avatar icons at the top in maybe a horizontal strip form.

I figure you have that code in the MooTools Recent Visitors Module. You would need to do the same sql join on the JG group table and add the URL string group ID grabber gizmo I saw in there, but seems like it would work just swell.

just a suggestion
