I don't think it's a good idea at all Sir Steve. I use the E-Mail that comes with my ISP, but alot of people don't. Not to mention there is those smaller ISP's that don't offer E-Mail service. I'd hate to have many decent forumites get excluded, in an attempt to cut down on the less then steller ones that have been plauging the forums as of late.
