Why do people get upset about a phone number? That's like a 1/2 step above an email address. Don't you have a Google Voice number (not on a Gmail account you use) or something for things like that?
Is that why my comment was down voted? LOL Weird, I don't know about Yil Yak but using a Google Voice number has never been a problem before for me. Maybe I don't use the right services? People who only use a VOIP number are out of luck I guess? I take it back... I wouldn't use that service either.
