I have been entering many of the PCA events into our calendar:
http://gt2gt3cup.org/calendar.php?c=1 with links to event information or registration pages; it is a slow process as PCA holds over 600 track events a year, I am ~60% done with the east coast events, could not make it to mid-west or west yet.
If you have events, enter it to the calendar, so it is in one place.
