My second life username is: MCFUNTOWN (why can't I change this!)
First of all don't change MCFUNTOWN! IT'S HILARIOUS! Second, I agree with moirakathleen, Exploring different sims and places tha interest you can be fun. Join some groups! Oh and if you wanmt to learn how to do certain things in world Youtube is always a good source as well. But most importantly be yourself, be resepctful and keep having Mcfun!!!
