I've been tri-boxing and starting to love it atm.. but i found that i am leveling so fast (lvl 33 atm) that i am so seriously out of gold to learn new skills !!

my main is getting skinning and herbalism and one of my alt is getting tailoring and enchanting (to disenchant items from tailoring and selling the mats). but the money is still not enough for me to learn all my skills..

what do you guys do to get those gold to learn ya skills? gold farming?
