It is phplinkdirectory v2.1 (free version). You can easily get it and make it yourself. Go to phplinkdirectory.com and download from there. Owner of this directory remove footer linkback to phplinkdirectory.com Not good policy.
What's so special about this directory? It seems like a normal phpld directory with a free template. There are dozens of free templates available for phpld. Just do a search in Google.
Don, it has link details page too i suppose it is 3x version and it is a script of $75 which does not need linking back to the phpld site.
Oh didn't check that. He probably used the free link details page Mod for 2.1 version, and made it look like 3x I think it belongs to a member gio here.
