Thanks for the feedback we're cloelcting it (and by we , I mean the NowWeb team, which is a ITS/Communications committee that deals with web-related projects and requests). In a few weeks we'll evaluate the responses and see what tweaks we should make to the calendar and the digest. Adding additional fields is doable, but we wanted to keep the digest very scannable the more fields we add, the harder it can be to read. Adding the presenter and sponsor might not bulk things up too badly, but the full event description would. We'll also review the timing of the digest.
