Eventually, in some time, I shall be allowed to make a server acc, correct right? but I was wondering if there is anything else I can do with my profile, I remember reading I have to submit a character profile to the wiki before level 40, but is that the only thing? Can someone tell me what else should I do, optional or not.
I'd wait until you're confident that you want to play the character before you do much with their profile other than establishing a personality to yourself. All you have to do to become a Grunt these days, is submit the profile before your character hits level fifty (After playing said character, of course.) Then, you just be active here for a month or so and submit a Questionnaire to become a grunt, if you have the approved profile, of course!
There's not much that you need to do right now, other than wait, that I can think of!
Good luck, and have fun!
