Social Groups Avatars
It appears the Social Groups section appears to have big ? pictures or avatars associated with each member for the members list.
Are you going to allow members to upload pictures for their Social Groups membership (I highly doubt it since LQ doesn't allow forum avatars)? If not, perhaps it needs some cleanup to only supply a text list of members, the pictures take up a lot of real estate and I'd imagine once there's a lot of members, these will take up more space than necessary on the specific group pages.
