Try not to double post. It's somewhat disruptive, and you don't want to make it a habit. Feel free to edit your post, however, as it is an efficent way of adding more comments.
This forum isn't a very big site on competitive playing, but I'm allowing myself to direct you to the following forum:
http://www.smashboards.com
Here, you can find tournament information according to your area. You're free to enter one and see where you stand.
I'd like not to be have to advertise like this, but since the forum is pretty strict on online gamers meeting each other, this is your next best option. The site, so far, has had no trouble with anyone faking a tournament as a trap to lure anyone into a dangerous situation, and they have a wide reputation of holding very elaborate tournaments.
Nonetheless, keep in mind the obvious rules of meeting someone from the internet and stay wary, especially if you're someone under the age of 18.

Feel free to bring the issue to the Staff Forum. I'd rather it not be deleted and have it judged by the admin themselves.
