While I am all for techy stuff, I think it can backfire when it comes to things like wedding invitations. My dad received an invitation a couple of weeks ago, and the reply card only had a website on it for him to send his reply. There was no phone number included in the invitation. My dad is 67 years old, and has never used a computer in his life. I'm sure many people receiving invites from this particular couple are not computer literate. People should be aware of who their audience is before sending out these kinds of invitations.
