Hello and welcome to PC!
You will find out everything eventually but if you need any help feel free to VM/PM me and i will help you to the best of my ability. Also you are sure to make many friends as people around here , well in my opinion anyway, are generally friendly! Just try not to get on anybody's bad side (especially the mods and admins!) by following the rules and respecting other peoples opinions!
Well anyway have fun and i will see you around!
