But what about your party then? You would have to buy these special cards to invite your friends, and with generic solution you can put these invite links on your custom made postcards, in your e-mails, etc. On the other hand I'm just curious how many wedding parties are now organized using Facebook's Events feature ;) (interesting to note: FB Events do not remind to confirm your attendance as well)
