We've rewritten this somewhat this week and now it works (IMO) MUCH better..

Buttons are

Top maps to offset 0/1
< Prev maps to offset -100
Next > maps to offset +100
Next >> maps to offset +500

We do have a <<Prev too, but need some css changes to align it yet, so it's not in right now.

Jumptorank, works by entering an offset rank, pressing enter invokes the jump

Search, this is enabled on users.php, teams.php, combined boinc users and combined boinc teams for now. It will return a results set in ranking order of everything taking whatever you put in and adding a % to the end.

The resulting search page provides links to the offsets as well as the individual pages.
