I am thinking to create a webdirectory but i am confuse which script is best for that. but most be free script plz help me?
Probably hundreds of threads on this already - try a search and you will find all the information you need on the topic.
What features do you require for it to be best for you? Btw, why do people asking questions use so much? Your question is intentionally sarcastic?
As per my personal experience, my static, human edited, HTML web directory is doing great... so it is the best so far. but, as far as, script is concern, i think java script has many issues with search engines, so php wins the race... u shud carefully analyse all the views and than take final decision... also update us abt u r final decision...
phpLD is the best by far but like the 2nd post said, there are hundreds of threads with this question
