I sent you a Message from your profile page just now (hope you don't mind). See if you receive it. If not, it could be a problem due to some email setting with your ISP (such as whitelist/blacklist). It's probably fine, but who knows. Whenever my parents change anything (unplug the modem, move 2 apartments over, change PCs, most anything at all), emails from ME (and only me) shut off. What fun, right? They have to contact their ISP to get me "whitelisted" again. Maybe a Message test will help narrow it down -- but you might only need to do a little modification of your "home coordinates" or the Cache search distance.
