Have you guys ever come crossed www.af1234.com? It's a website directory for mobiles. I am thinking about how to build a good website directory, would you guys give me some ideas?

As I just viewed web directory which you mentioned but still it is in under development process. If you want web directory to be live in short period of time then you must buy web directory script which you like and later make changes in that script as per your need.

I think it will be better if we develop our own site.
Should you guys know the popular and hot sites of our country?

We can form a team and design something like that
