This next problem may be related to the other problems described in previous posts here and here. But in case it's different, I thought I'd add it to the "list" of issues.

If you are viewing the list of members and you resize the window to make it narrower, or if you try to view the members list on a small-screened device like a mobile phone (in my case, a phone running Windows Phone 7.5), the column titles (Group Member / Rank / Posts / Website / Joined) all disappear except the first one (Group Member). This makes it impossible to sort members by anything other than username.
I know you're prioritizing basic functionality of the PC website above issues with mobile/tablet display, and that makes sense. No rush. As others have said, you're doing a great job; keep up the good work.
Cheers,
Eric
