We now have a calendar available on NYGF that anyone can add events to. You will see a link in the navbar to vitew it and here is how to use it.
  1. Create a thread as you normally would in the appropriate section.
  2. After the thread has been created, click the "Thread Tools" menu then "Calendar Add"

  3. A window will pop up asking you for the date. Select a single day or click and hold the mouse on multiple days for a date range. You can also click Advanced for date range
    or multi-day events
  4. The event has been added to the calendar
To remove an event or edit an event (to edit, you need to remove then re-add), from within the thread click "Thread Tools", then "Calendar Remove"

There is a help thread here
