Perl Monks User Search has been updated to reduce the load on the servers. It also should be easier to navigate through a user's node list, now. You can specify how much nodes you want it to display per page. See the ' Perl Monks User Search Default Length' option under 'Miscellaneous' in user settings to make it your default. It defaults to fifty, now.
In the near future there will be an option to only list user nodes of a specified type.
If you have any problems/questions, please let me know.
