geez...no one? when someone likes what you have to say they give you rep points "possed" or "pozzed" or "pos" = positive
if they don't you get "negged" = negative reps
they're easy to accumulate if a lot of members like what you have to say all at once....number of posts don't count a whole lot either because a lot of people come over from other sites that everyone knows already
the best way to look over sources it to look at the general feedback within their individual forums or try to look for someone where the rep has been helpful to you and you think you can trust <<< see what I did there?
