your best bet is to buy your own domain, it can cost as little as 9$ a year and adding one e-mail add. costs anothr 3 or 4…
i have a yahoo, hotmail, gmail, univeristy and my own domain email addresses… i use the first two for signing up to rubbish, each one has its different rubbish use, (i started with a yahoo account when pop was free), gmail as an ‘important’ one for signups and registrations that i like to check regularly thourgh my e-mail client and my domain for my friends and family.
its good to have an e-mail address which you can have for life, that way its urs and you wont risk losing pop privilages.
