Support Forum

A few problems when I'm adding members to usergroups:

1. I have a few Wordpress Members that don't show up as forum members.  Everything was set up at the same time, and in the same way, so I don't know why a few members aren't listed in the forum area (I can't add them to usergroups, or pull them up in a member search no matter what I use as the search criteria - they just aren't there).  Is there a way to add them somehow through the database or something?  I really need to be able to add some of these users to special usergroups.  This issue is critical, the next two should eventually be addressed, but aren't a big deal.
2. In Manage Usergroups -> Add Members, when I add a name in the "Filter List" box, it does fine with single words.  If I add a first and last name (with a space in the middle), the Eligible Members box completely disappears and I have to cancel out of the Add Members area and start over. 
3. Members who are listed in a usergroup ("Manage Usergroups -> Show/Hide Members area) are listed with bullet points and vertically in the first letter section, and then horizontally without bullet points (not a big deal, but doesn't look good)
