Hello! To give a rep you see the comment box in a thread....then on the left side under feedback score there are 3 icons...1st one tells if the person is online (green dot) , 2nd one is to give reps, click & a box comes up to put a message, 3rd one is to report someone (never used it!).
Glad to help!

thanks for the rep,wish I could also sort out how to give a rep.....
