SaneBox is basically a webtool that filters-through your web-based email (on Yahoo!, Gmail, Outlook, etc.) to leave only the 'important' messages in your inbox, making a new folder (where all the 'unimportant' mail goes) in your web-based account. (They claim the program will 'learn' to keep emails 'important' if you move them from the "SaneLater"-folder back to the Inbox ... just got SaneMail, so I haven't seen it.) To extend the FREE period (two weeks?) to 'forever,' invite friends! This is another place where I'm not sure: aLog In claims that you get your first month for FREE and another month for friends who join, but the slightly-differing invite-links Sanemail gives you (Log In,Log In?) say that--rather than 'a FREE month to start & 30 more days for each friend who signs-on'--it's 'two weeks FREE to start (+$5 toward a paying subscription) & five more dollars-off for every friend who signs-on. Like I said, the blog was from 'last summer' (or from a summer before that), so it looks like 'the price has gone up.' But ... you never know, maybe they'll feel generous ...
