Whatever happened to the R.S.V.P.?

I am very troubled today about the R.S.V.P.

Does anyone know where it went? I can't seem to find it! Over the past year, I have coordinated many business events - and many of the attendees it seems, could not locate that R.S.V.P. either!

I was told at one of these events (that had primarily 21-40 year olds in attendance) - that "we just don't R.S.V.P. anymore....it's not really necessary.....people just don't do it." But they do seem to show up!

Now I'm not sure if the people that don't know how to R.S.V.P. have never planned an event before - so they don't realize how important it is in the planning of events to know about how many people are attending - or if it's that people today just have way too much on their plates and not enough time to even R.S.V.P. at all - or if the name of responding to an invitation has just changed and I'm so out of the loop that people don't even know what I'm asking for when I put R.S.V.P. on an invitation!

Maybe there is new "R.S.V.P." lingo. Is there a "tweet" version for use on twitter? Or perhaps an "e-R.S.V.P" for using evite or another similar on line invitation tool?

Has the R.S.V.P. simply just gone away? Maybe people today don't need to let each other know if they are attending an event or not. It must just be socially "cool" to show up at something when you feel like it, and not show up when you don't.

I think I will show up at the next event I'm invited to - without giving them an R.S.V.P. so that I can be cool, too!
