well - for some groups it'd be nice, if one (the author of the group) set the sort by either nums/name: The "SL - One Day 1 Problem"(http://www.goproblems.com/usergroup.html?id=113) group, for one, would make alot of sense, if it was sortetd, by name - As I didn't start putting problems, in their order... (Going back to other problems'll cause them being sorted in a "messy" way - as their names correspond to dates..)
