The easiest way I have found so far to keep track of my FTFs is to create a public bookmark list where each FTF can be listed.
Here on Project-GC you can go into your settings and modify the list used to track your FTF caches.
The best part is, all of the dates and orders of your FTFs as well as FTF stats can be generated from those GC codes in your bookmark list.
Hope this helps!
