user2userpoints removing points substraction while giving points

Hey,

On my website I would like to offer people to give other people points. Something like user A "cheers" user B when he thinks user B has done a great job (applied to this site: I give the person who responds best to this topic 1 cheer).

The userpoints module looks ideal. But I have some questions for the more experienced userpoints user/developer:

- Is it possible with userpoints to have a different pool of points. I would like to seperate the "cheers" of the user point gained by activity
- Is it possible to eliminate the transaction. So for example, each cheer equals 1 point. A user can give an unlimited number of points, but he is limited to one point per user. When a point/cheer is given, no substraction from the own cheers is done.

user2userpoints seems to do the trick a bit, but misses a setting where you can eliminate the substraction of points. It should also be possible to set a standard number of userpoints that can be given (in my case always 1). Giving points to a user should happen by means of a little ajax call.

So someone has a solution / module for this, or will I have to implement this myself?

Thanks for any tips!
