When i create categories for my blog they are sorted by their ID tag (i guess), but in order that first categorie stays on bottom then second goes over then the third over second etc. (well if u have ever created categorie you probably know what am i talking about)
I searched forum but i didn't find any (easy) ways to sort categories.
It would be a good idea to develop some way in admin panel.
And, btw, wordpress is fine!
