Kopete does show below the buddy list a message telling you that someone has added you. You have the option to block or allow that contact to see your presence. When you click block, the message disappears, but the space used is not recovered. You end up with an empty space below the contact list. There is no handle to drag the section manually back to the bottom either.
It would be nice if this section does collapse to give as much space as possible to the buddy list.
Anyway I love Kopete!!!
