I've started using Tribal Pages too. I find it a lot more flexible than FMT (mines an older version though). I must admit I stopped using FMT ages ago - I wish I could turn the hints off, om´n the version I've got even if I reject a hint, it doesn't disapear
I like that on Tribal Pages the parents of a child can be something other than married, and it gives more options for dates, such as "before" a certain date, "after" a certain date, "about" and so on.
I also have my tree on Ancestry, so I update both (not finished putting everyone on tribal pages yet though). When your tree is finished you can also order a cd with it on, which according to their blurb is just like using tribal pages - I may do that at some point, if only so I have a backup of my tree.
