Really, you can! Make as many edits as you wish. After all, that's what Wikipedia is about.
If you're here to vandalize my user page, why don't you turn back and become a constructive editor? Wikipedia is always in need of more constructive editors, and you can help.
If you wish to make constructive edits to my user page, feel free to do so; I will assume good faith with your edits. Find a mistake or error? Correct it! Think something is missing? Add it!
Comments, questions, inquires, etc. should go to my talk page. While you're at it, it would be appreciated if you signed my guestbook.
