I cannot seem to use Find Player to get a list of players
in a specified range of ratings.

For example, I queried with:
name: <blank>
rated btwn: 1250 and 1350
check boxes: <blank>
and click search

then I get a list of 20 provisional players, all 1200.

Am I missing something?

I think it is designed to find one particular player,not a whole list.
But if you do it like you did,but put a letter,say M,instead of leaving the name blank,you'll get 20 players in the selected rating range whose handles begin with an M.Maybe that's a lil better?

Sir lot.

why dont you have a look at

you can change the number in the url to jump around quite quickly

This is currently broken - but is about to be fixed on the next release.
