No, but I don't really need one since I'm not trying to be a professional. I've heard good things about [link] though. It looks like you have more flexibility with it, and it's free. There are probably tons of other sites you could use that don't require you keep up a subscription fee. (Or are portfolios free on dA now? I can't keep track.)
