Derek Davis and Connie Hatch are putting the Calendar together from various lists, emails and suggestions. If anyone has ideas as to the best ways to display it, as well as items to include (or exclude), please let us know. Use this contact form.
At this point, what seems best is for us to maintain an Excel file offline, update it as needed, then upload it to the Calendar page. Not sure yet how well this would work, and it may take extra effort. But we do need to update offline, rather than chance too many people overlapping with each other if we used an updatable online calendar. Hope this makes sense.
