Yeah thing is both account i have on benediction have 60's hordes on them and i can't make an alliance unless the server is free of hordeYou can always "send" gold to yourself via the neutral AH, but you lose 15% I think.
Just post an item maybe a blacksmith hammer for 2k gold, buy it from your horde character and you'll get the gold transferred minus AH fee (which is higher for the neutral AH.)
