Someone may correct me if I'm wrong here, but except for the mods (moderators) the titles have nothing to do with skill level. They change with the number of posts. No, I don't know how many posts one needs to be a ::cough:: Level 5 Apprentice
MODS, of course, are board moderators who keep everyone on their toes
And i think, if i remember what i set that to, it's every 50 or 100 posts gets you to the next level.
It's just one of those 'default' BB type things to help intice people toward being active on the board. And i've made a new rule to add to this lately... anyone reaching 1000 posts can choose their own "title".
So when you reach 1000 posts, be sure and let me know!
