While surfing around the site here I found a place to check your quit calendar. If you click on your profile then go to View profile. On the row of links under your profile link click My quit status. There may be other ways to get there but thought this was pretty neat. I not sure how to do a screen shot to show you but I will learn.
You can also access it in the Profile Hovercard. Simply highlight over a persons username and then look for the EX logo button in the lower left of their Hovercard as seen in screenshot below.
