Have you ever tried another virtual world besides SL? I've tried a few and right now I'm checking out another one that seems promising.
Kitely is not new - its been around for a few years from what I can gather - but its a neat idea with different structures and the easy ability to obtain your own sim, to create your own world!
And now, I'm on a mission to figure out how to export my creations to Kitely, to see if I can make a decent looking avatar there, and to see what places I can explore! Wish me luck!
