Hi! I'm a child of the 80's and a product of divorce. I'm sort of new at Wikipedia as a user, but have been a longtime avid admirer of the site. Decided to finally start helping contribute, and must admit it's sort of addicting :) Am still learning the ropes a bit, so feel free to drop a line on my talk page and let me know if I do anything incorrectly.
