I think you mean sorting/ordering, and yeah... I was wondering about that too.

I found it quite fun to look for hard or easy problems by using the sort by "SOLVED BY"

Perhaps you've not been aware of the recent problems we had with server overload. Consequently I had to rewrite all the scripts to make use of a caching system for pages and it is taking me almost every waking moment to do. Most features have now been restored, but one or two other things are still waiting to be ported across the new system; some simply cannot be translated across. However, this is one which I can do and is next on my "to do" list.

I read it (after posting here), great work for getting it back online

I would advise to transfer some more cpu power from the server to the client though, current computers are quite fast and javascript has more than enough options to allow sorting and other stuff, it will save you bandwidth (not another page to load) and cpu power for the database (sorting can be quite heavy if there is no index or if you've got a complex query which does not allow the usage of indexes)

If there is anything I can do to help please tell me, I've got quite some experience with high-load websites and know what/where to optimize.
