Welcome to the boards Tenshii! I think we will get along pretty well.
A bit of advice: you should start browsing the Sheik board here if you haven't gone there already:
http://smashboards.com/forums/sheik.128/
this will give you a place to communicate with other Sheik mains on bettering your play. Also, update your location (if you choose to) so you can maybe get to know some other people from where you live.
I can relate to wanting to go to a tournament. I have to get my license, or beg a lot before I go to a tournament around Houston
Hope you enjoy your time here!
