Well, I guess I can post in here now.
I started out with 15k about three weeks ago. Since then, I've powerleveled four professions, donated about 4k gold to my guild, bought the spellpower enchant for 3k off the AH, spent 2.5k on a couple boe's for my priest, and spent tons of money on other stuff that I can't remember off the top of my head. And yet, somehow, I cleared 30k liquid tonight. And I have plenty of mats to help me keep going (including a couple nobles decks in my bank).
I think I'm getting pretty good at this goldmaking thing.
Well, I spoke too soon. Too many good deals popped up. I'm down to 15k temporarily. But a Mechano-hog, two Nobles Decks, 50 raw epic gems, three fully stocked glyph bank alts, and a bank full of herbs suggests I'll recover in time.
