What does "PRO" or "MODERATOR" mean by photo

[Sharon R.]

Since I just found you guys today - I think I don't know what I am doing!?! LOL
I may have already made some mistakes. To get to go to "Marketplace", what do you need to do, or pay, etc.? I think I somehow posted in Comm. RE and it should be somewhere else regarding wholesalers - if I did I am sorry. I may be a little rustier (if that is a word) at this than I thought! Any help???
