Hello! First and foremost, your plugin is amazing!

I was wondering if I found some kind of a bug… and I don't think the forum had anything related to this topic yet. I am developing a website that requires constant updating of Role Groups. When I go to Users > Role Groups to create a new group, there is a section to add the group members by typing in the username. No matter what I type in, or even if I type in the exact username that exists, it displays all the users in the search result box. This is also the case when you're in one of the user profile and search for groups. The "Use jQuery selection UI" option is selected in the Options (by default setting). I discovered that by deselecting this, the checklist UI works great. I like that you have provided the different UI options for this plugin, and wanted to let you know of this issue that I'm having (especially since the search/results interface is the default setting, and that's the one that is not working).

I'm testing on a fresh installation of the latest Wordpress 3.2.1 and Role Scoper 1.3.45. The only plugins that I'm using is Members and Import Users from CSV, both of which are deactivated after using them to add Roles and Users.

Relating to this, I was wondering if there is a way to search users using their first name or last name, instead of their user names. 

Thank you!

The required change to fix User Search with the jQuery UI enabled is line 12 in role-scoper/admin/user_query_rs.php :

That will be included in the next RS release.
