Since you have registered an account, I am assuming good faith and hoping that you intended to do more than vandalize pages. If this is the case, you're welcome to continue editing Wikipedia, so long as these edits are constructive. Please see Wikipedia's blocking policy and what constitutes vandalism; such actions are not tolerated on Wikipedia, and are not taken lightly.
Here are a few links you might find useful:
