There should be a profile searcher on AG cause in cause anyone's got freinds or family ETC on AG and can't find them if there was a profile searcher they would find them all post the faved =] an unfaved =[
When you go on someones profile the address is something like "http://armorgames.com/user/Thomas1st2/". If you know someones user name you can just type it in where I have bolded (where your user name would be) that should take you to their page.
I don;t think a profile search itself is needed right now to be honest and I can;t see them amking one. but I hope th above tip hellped.
