I'm just writing this, so it might be useful for some of you using this mod.
I think there won't be a problem for small forums, but I have a huge forum, with more than 35000 users, and a very big problem appeared.
After I installed this mod, forum started using enormous CPU resources, especially RAM. For a few days i was searching for an answer, and i found out that Ultimate points queries was causing it. But only the ones in index.php, which actually aren't useful, unless you want to show the Total points in forum, or Most rich users.
So if you are having the server "lag" problem, just remove all the Ultimate Points code from index.php.
I guess, it should be necessary only for big forums. Cheers
