I promise to not be stalking you

I read in another post on another board (that's the not stalking part) where you said you'd be webcasting your wedding. I'm curious how you told people about this.
Did you invite everyone to your Vegas wedding and let them know that if they couldn't make it, then it would be webcast? Or did you always plan to have the small Vegas wedding and anyone invited to the reception could watch the webcast...?
Just curious on the details!
