When? Someone should really either fix the link in the OP or give the info there... I'm not sure what this Anyvite site is, but this is giving me a horrible first impression for something that may or may not even be their fault. Unfortunate, but such are first impressions...

Anyvite is a YC company. Their Tweetvite service - http://twvt.us - is baller. I've never actually used the old-school Anyvite service.
