if you look at the group overview page, e.g. for http://developer.qt.nokia.com/groups/qt_german/members where more members than for one page are displayed, you get different behavior depending on the browser width:

If 4 members are in a row, the last row is full with four members, if only 2 per row, it's also ok. But if only 3 members in one row are displayed, the last row only contains 2 members. So it's not directly clear that there is a second page (as the link perhaps is not scolled in).
