What do you guys use for directory management software? I looked at powerseek and hyperseek, but I bet there's a lot more out there. It's kind of like a forum... the more you get into developing your own, the more you realize that there are a lot of features out there that you really want.
I am very happy with Linker. cpDynaLinks is another good option, though I had odd difficulties with it under FreeBSD. Biz Directory Free PHP Directory Script is another script to look at. It has an array of pricing options. Gossamer Threads is a purely commercial play, much like two you mentioned above.
both cplinks and cpdynalinks are good. I am using that on 3 websites. Good One. The guy who owns them is Chris, a very nice guy.
