Hello Quacker. I think you want to sign up to one of the email service providers so that you can retain a permanent account. That is quite simple. All you have to do is choose a email service provider, click on the sign up link and then enter your information and preferred email ID.
To simplify things, I am listing some email service providers that you might want to use. You can use or all of them but that will just complicate matters further. I would advise, that you have at least two accounts so that you can use one as your primary email address which you could use for trusted contacts and transaction purposes and the other one as your secondary email address, which you can use when signing up at various sites. This is just a suggestion though, you can easily have as many email addresses as you see fit. :)
IN
Yahoo!
Gmail
Hotmail
Rediff Mail
There are many more but these one are the best and most reliable. Also, they are widely known so they should be acceptable on most sites and Forums. They also provide an import wizard so you should be able to import all your existing contacts and information into your new account and an announce feature which means you can update all your contacts to your new email address with a single click.
Just use the one that suits you best. Hope that helps. :)
