Calendars are fixed... sort of

Well apparently the way the forum calendar work is by adding entries via new threads and I've been poking around the administration panel and fail to see any "do not notify if a thread is added to this category" option.

So what I did is making the calendar entries into a separate category and add a new "tests and homework" category for assignments that needs it's own thread, I'm afraid I can't disable the notifications for new calendar posts though.
