Paradox, Hoikas, Aloys and I have added a calendar onto the forum. It's not open to user posts yet (since we're unable to delete events), but the Council will hopefully be adding events to it as they come.
If you have an event that you think should be added but hasn't been added yet, PM a Councilor (Aloys, ChaosSong, Hoikas, Paradox, or myself).
Enjoy
