Yo so I know there's often threads about vote swaying etc... no one wants to use your real email address b/c of spam and all that crap.
I don't know if anyone has posted this in the past but there's a couple sites like http://10minutemail.com/
which give you a fully working email address for 10 minutes (thus the name) but you can extend the time if needed.
This works great for registering for shit that you will never need to get emails for or don't want to worry about spam etc....
I've been using it for quite a few things and it's quite dandy...hope this isn't a repost
