I wanted to give a shout out of thanks to Dave Wanta and Advanced Intellect. Dave has written a component called AspNetEmail. You may be asking yourself, "Email is built into .NET, so what?" Well, getting calendaring done is kindof a pain. I plugged in Dave's component and it just worked. I had a few questions and Dave knew the answers before I even asked. His components are well worth the money.
Yes, I'm using his control for quite a long time now. Also, doing mail-merge stuff is very easy. Just add a datatable and an e-mail template, and the mail merge is done. (a-sync, if you want!)
The thing with templates is really good. I'll have to find time to toy with this.
