Are you sure you lost it? To me your rep looks very high... Contacting an administrator will help.
I mean, to see your rep points is obviously by clicking on userCP and checking how much you've received.... If you didn't know that ^^ and what do you mean about 4 and 5? I believe you're talking about the rep power of what you've been giving...
Stop spamming this thread, if you don't know how to help him, stop posting :/
@Original post Either it was taken away by the admins because of you rep whoring or something along those lines, because i believe it is if you are caught asking for rep they take away 500, or If they massively deleted a bunch of threads you got repped in for whatever reason. Either way, i'd advise you to contact an admin about this
This problem is something you have to contact an admin through PMs only not on a thread so everyone can see and comment on it. Coming on here and continuing this thread is only making it worse for you. Please use your common sense if you have any.
