Playing the Wow auction house

[foal]

I got back into WoW a couple weeks ago, but the only aspect of the game I'm really interested in is the auction house. I played a skinning/mining rogue up to level 20 just to have some funds to get started with, but I now find that spending all my time on my level 1 auction character is much more efficient.

So far I've mainly been dealing in linen cloth and light leather and am gradually moving into some slightly more expensive items like mageweave cloth. I'm thinking that with the new expansion in the works, cold resist items should go up significantly in value. I'd like to stock up on them if I can actually make enough funds (all I have right now is about 100g worth of leather and cloth). Oh and I use the program "auctioneer" and it's not really all that helpful so far, but it doesn't hurt.

Anyone else into this?
