Well, I gotta say it ... for all of its frustrations and whatnot, FM is a pretty fine product. I've been using it for years and still marvel at its features. Godspeed to you guys.
Having said that, a couple of minor suggestions today - just to keep it all from going to your heads:
1) Dunno about other users but I'd sure find a toolbar button for switching between yield types (ROI and TWR) to be real handy,
2) The forum as it exists is pretty much: User writes something, Mark replies, end of discussion. Could you dedicate and even promote a forum where users can discuss FM and related subjects between themselves?
