I was very glad to see a reasonable crowd and many familiar faces during our last SgDotNet's 23rd (April) user group meeting. After all, SgDotNet is going to be 2-years old!
For those who are interested in the slide deck, you can get it from this post attachment. Demo code files are not included but you can contact me if you are keen on getting a copy.
I will be presenting ASP.NET 2.0 WebPart Development in one of the upcoming user group meetings (probably in July and together with SharePoint 2007 presentation by KitKai).
