When Google first launched gmail, I grabbed an address to use as my (hopefully) permanent email address. I grew tired of obtaining a new address every time my ISP changed and then blasting this address to everyone I knew. Since I access my email from home, work and my mobile phone, I was stuck with having to put up with marking emails as read multiple times.
This week Google is adding IMAP support for all gmail accounts (my account still is not enabled.) This will allow you to mark an email read from any client and it will be marked that way no matter what method you use to access your email. More on this at :
