Do not use the e-mail address that you get from your ISP (Internet Service Provider), such as AOL, Comcast, Wow, RoadRunner, etc. Once you give out that address you'll be tied to it forever and it'll be impossible to get people to correct your address. Plus you'll never be able to leave that service
Get something you can keep forever like a gMail.com account or better yet, something that comes with your web site domain so you can use an address like me@mywebspot.com that you'll always own.
You can do this for as little as $2.99 a month.
