Thanks guys. That's what I was worried about.

Do you have any other solution? Currently I have my mom set up using the Cox webmail account, but that's inconvenient and she can't check the mail if my dad's already downloaded it into OE. Is there any other way of sharing a single email account among two computers? They're on a simple wireless network, with my dad wired to the WAP and my mom with a Linksys WUSB11. He's running XP, she's running 98 (SE I think).
