Have you ever tried to contact someone who looked like they had some great info on your ancestors, but their email account didn't work any more?!!! You don't want that to happen to someone trying to contact you either! It's really a good idea when posting your genealogy info online, to setup and use an email address specifically for your genealogy work. And it's even more important that your email address is not tied to your internet service provider! Choose a free email service like gmail, yahoo, or hotmail for example.
I've moved over a dozen times in the last 15 years, and my internet provider changed at each location, but since I have both a yahoo and a gmail email address, I've never lost contact with anyone, and folks can still reach me regarding queries and posts I've made to genealogy boards a decade ago.!
