Can anyone explain the difference to me?

Just for the heck of it (I wanted to see how badly I should feel for d/l'ing beatnick skinz and not having submitted any yet...they are very cool, as is the app btw), I was looking at my profile thingy, and now my title on the first line is "Apprentice", but my User Level is still a "2". The User Level was a 2 when I first came onboard, so again I am wondering if it signifies anything?

Just curious, I don't give a flyin' rat fart if it is my popularity level or anything...just wondering the definitions...
