I haven't filed this in Projects as it might just be a misunderstanding. On the User CP panel on the home page, my rep points are shown as 11. But if I actually go in to my profile, it says 27. Also, how do I find out how many rep points another user has?
Rep points and rep power are two different things.
The rep power influences how much of a difference your repping makes to others. i.e how many rep points they get from you
Rep power is based an a few different criteria such as post count, current rep points etc..
