oops, sorry Doug, think I failed to mention that it's useful to check in through the main page frequently for just such occasions as this....'twas the same mistake I made way back when
If the campaign is still live/ongoing, they will shunt it down below the main campaign under "Current Campaigns" in favour of the latest or most urgent I think. As the sailboat campaign has disappeared altogether, I think you can safely assume it is now closed.
Although access to any of the older closed campaigns through links posted here or your own saved links it's really only for exploration out for your own personal interest.
Another tip I find useful on certain campaigns is zooming out the TN screen to -5 gives you reveals the size of the map you are on and current position....how much you have yet to clear By zooming out your browser screen to the max reveals the map under the grid which is useful when you aren't sure if it's cloud you are seeing on smoke plooms in say a wild fire campaign. So in that respect, access to older campaigns does have it's uses, particularly for newbiesw
