What is the e-Card script?

I client of mine has provided two links to websites with e-card functionality. When I checked out the two sites, the e-cards appear so similar that I believe they must the same script. However I can’t seem to locate anything in the page code or by Google search that would indicate what it is. Any thoughts?

Here are the websites:


There are two parts to this. There is the front-side that does the popout and the backside that does the actual e-card. The backside part of this is relatively simple in principle. It gets more complicated if you start adding in user administration etc… The front-side uses a jquery slideout. I don’t see the same scripts in their source code.

e-cards are simple wishing script where people send their wished on different occassion from one server to another email client.
