Why Signup for Free Service?
From mail2web.com Wiki
Why do I need to sign up to use a free service?
Answer: By signing up for a mail2web.com Personal Webmail, you'll be able to reserver your mail2web.com Username, and save some information on your own customized home page. Because we need to save some of this information, you'll have to sign up, log in, and set up your Personal Webmail account for future usage.
If you prefer not to sign up, you can continue to use mail2web.com for free simply from http://www.mail2web.com.
