I invested a lot today. Bought 60 Expert Cookbooks, bid on 70+ lvl 41-50 armor to disenchant, and Thelnia's stock also increased greatly. The wool cloths returned from the common AH, I relisted them. Sold lot of mageweave cloth, steel bar.
Today I finally quested, made it to 36.5, mostly in Strangletorn. Will continue questing in Desolace.
The daily balance is 1815G, 138 auctions, 28 bids, 1680G at Thelnia.
I updated /gquit incorporating ideas from commenters and Larísa.
