I'm gonna try and crank out this forum plug-in that I've had on my mind for awhile, by the end of the weekend. I'm not saying it has to be polished, but I'm gonna try and make it happen.
There's some challenge to it because it includes a Silverlight app, which I've never done before. Already I'm blown away by what's included in the runtime. The networking stack is pretty awesome. I've not looked into animation or anything, but the UI capability alone is outstanding.
If I can figure this out, I can easily add a feature to CoasterBuzz that a lot of people have been asking for.
