Err... It sees to me like it always lists all hits for the letter you've chosen, for example it shows me about 150 groups on that link (I have set it to show 100 hits per page).
Problem "fixed" for now.
The way I do the sorting got screwed by a group name entry starting with a #.
I'll need to do a complete rewrite of the sorting some day :|
just renamed the group for now }:o)
