A birthday greeting is a friendly gesture but what I really want in a calendar is a list of upcoming wargame events. How about a list of top (worldwide) conventions? ...with links to the convention websites.... or maybe a feature: "on this day in history" etc.
Info like that has to be curated, copywritten, validated, edited and uploaded, whereas the birthdays can be automatically displayed.
Simply put, given day-to-day jobs and more pressing moderation and admin issues, we didn't have time for that.
