I highly recommend you sign up for Apex Mail - It's free, and it features the option to foward all e-mail you get to your real e-mail address. So, you don't have to give out your e-mail address if you don't want to. You can even make your reply from the box, so no one knows your real e-mail address. I think the quota is 3 MB.
Just wanted to let you all know that.
