I think you are talking about user assistant? Im not to sure
But just so you know;
-You need at least 10 posts (if you soam the forums the application will be declined)
-If you ask other staff available to vote on your poll you can decrease the chances of you getting UA
-It's no use asking users what they thing the chances of you getting UA will be. This can be done privately of course but there is no need on the forums as users cannot vote. Only User Assistants and up
-This one goes without saying but dont bribe User Assistants, as the staff have creative
There are just some notes that i think you should know

and im not trying to be harsh just realistic. And dont let this post make you not want to be a UA. I am just saying what you should do in order to become UA
