Theres a list of directory scripts here http://www.directorytrials.com/complete-list-of-directory-scripts/ each should have what you're looking for. Im not sure about google indexation, im not sure thats down to the script, otherwise we would all be dumping one script for another.
People, I know many directory scripts, on hotscripts I see 100s of directory scripts. But which script is the best for google fast indexation? What do you think about that http://www.phplinkdirectory.com/articlescript/index.php
As i already said, its not as simple as that, being indexed is not down to the script, any script claiming theirs gets indexed faster is talking bollo.... One contributer to indexing is your content but other things affect it too, why do you think its the script that controls this?
Is there any simple directory script that is really simple I mean like something like DMOZ. Just a simple admin control to approve and delete and edit.
