My latest challenge is to learn everything there is about Sitefinity. When I first came to Falafel, one of my first assignments was to update some of Falafel's DNN modules, one of which was QuoteMax. This was a simple module that would manage a list of quotes and would pick one for display upon each page load. Of course, you might have a hard time saying any DNN module development was simple. In any case, this simple control would be my first try at custom Sitefinity development.
