Actually no :) now eSyndiCat is more directory software than a link exchange script. You have the possibility to create your own fields like dropdown boxes, radio, checkboxes, textareas, etc. For example you want a directory of local businesses. No problem, create additional fields like State, Zip, Address, Phone. You can easily do this yourself in admin panel. And later just ask for additional mod from our company that are quite cheep ;)
Forgive me if I've missed something, but eSyndicat looks like a link exchange script, while eDirectory is a proper business directory loaded with options for several different types of free and paid listings, etc, etc. It also has the best search features I've seen in a business directory, especially with the "miles from zip code" feature. I've been looking for the same thing for years, but there is absolutely no way I can afford the hefty price tag.
