I have three accounts, two of which i use, the 3rd i never developed. In the first account i have two paid member characters, in the 2nd i have two other characters, one of which is a 100 mage i've had since feb 07. I'd like to move the mage to the 1st account somehow so i can take advantage of the membership fee i'm already spending. (I had two paid accounts until the mage hit 100 and didn't use him much afterwards, but do occasionally like to pull him out of storage) Is it possible to merge accounts? I can delete the 2nd character in account 2 if necessary.

You'd probably want to open a support ticket on the NCsoft site and ask them that question unless you get a Dev wandering through this thread who can answer it...
