MyGnome: World of Warcraft
After having a lack of success with sites like wowdollar (got my account banned and wouldn't compensate) I found these guys.
Very friendly, helpful, and spoke fluent english.
One drawback - they'll only get you $7-8 USD per day, but I'm willing to go for that if I'm not getting screwed over.
Been renting to them for over a month now and couldn't be happier. 8 bucks a day still translates into a couple hundred a month for doing nothing.
Rating - 4/5
**UPDATE**
just to let you guys know (already told Farylon),
i talked to their AIM representative recently and they said that they've recently been having trouble with almost all of their rental companies. they've cut all ties with them and they're currently looking for more reliable companies.
he told me that they're taking a company hiatus until they can find some sites that are more willing to cooperate, and he mentioned something about maybe starting account sales as well as rental
hope that helps you guys who have been trying to contact them :P
