For reasons I won't detail (because I have already written about them), I don't use Prodatum. In short, it has some very good features; however, it had and may still have some issues. In fact several months ago when I went to Prodatum's bug reporting page, I saw people having issues that seemed very similar to what I had reported and made had suggestions about years ago.
For what its worth, I have had links to both Proteum and Prodatum on my site since I added links. I have not had the problems with Proteum that I had with Prodatum; however, it is strictly for Windows users, unlike Prodatum. For Mac and Linux users, so far as I have read, there is no choice.
Nevertheless, I have intentionally chosen to let people know about both editors. I think both have their own advantages. If a tool works for someone, great!
