Wednesday, December 27th, 2006>p>I was talking to a VC that recently said they had heard from four companies that want to do a “better evite”. That isn’t a high bar (ads in your face all over, not even showing dates in order!) but they have been slow coming.
Renkoo is a contender, and they have a very Ajax rich side to them, implemented with Dojo, and a splash of Comet.
Now that Renkoo is out there as a public beta, give it a twirl. One walk through creating a new invite will show you some very rich work, with forms filling out as you use each section, and then minimizing to get out of your way.
