i've been using yahoo for yrs. it's what i use to sign up for almost anything.*
the best thing is their spam filter.
<small>*things i sign up for that i am really uncertain about or definitely don't care to ever hear from again, i use one of my 3 hotmail accounts.
my personal email addy NEVER gets posted anywhere. only friends know that one.</small>
get spam in your inbox, just click the check box & mark it as spam. then it will go to your bulk folder which gets periodically automagically deleted. unless you're anal about it like i am & empty it daily yourself.
100 mg... that's just gonna make us all lazier than ever about keeping our mailboxes tidy.
