[quote=Channler]Yea, that would be pretty cool..
I'd like to start getting into modding.. Not sure where to start though

Do you have morrowind?
If so just make an island with a house or two on it. Simply get used to dragging stuff around, rotating, ect... That will be the same in oblivion. Learn to conect two cells, and change an item's size.
Also give dialoug a try, as I think it will be similar, and similer systems (in terms of variables and options, ect...) will be used for quests and AI.
Screw around with the new CS once you get it, read any tutorials that are availible.
If you want to work on an Oblivion mod that will be big and such, and just want to take it easy, give me an PM some time, I'm doing a huge underground tunnel network mod (think a TES flavored underdark), and the more people the better (more people=more tunnels=more quests=less suckiness)
I will shoot your dog if you don't read this post.
