Here's a tip for everyone. Don't use an e-mail that wont last forever.
There was a great Lifehacker article on this, but they swapped their site over to some crappy new layout so I can't find it.
Their suggestion was to buy a domain like [yourlastname].com and then redirect an email like [yourfirstname]@[yourlastname].com to your current comcast email or whatever.
Like Tonkka said though, you really shouldn't be using your ISP's email service. It's usually
much worse than standard email services like Yahoo or Gmail.
