Is there a way to get Facebook to acknowledge that my X10 email address is valid? Every time I try to enter my email into Facebook it says "You must enter a valid email address." It won't even send the confirmation, it just rejects it. I've tried to report this to them, but I get a generic "Thank you, your feedback will help us improve our service." Is there anything I can do to make Facebook acknowledge that this is a real email address?
