I use phpLD too, I've been considering moving over to PHPLynx though. I am currently building my own script that will blow all of them out of the water. You'll only see it on linkslinky, if I can ever get the site "officially" launched.
I am sorry if someone annoyed by my question. I came to know that we can easily start blogs or other structure easily with Joomla boards. I think these is some Joomla board for directories as well. I shall ask , Will I have to use any scripts if there would be something about directories in Joomla?
I am using index script...and i found it easy to learn and also i love to work with this,,,you can also use other scripting languages but try it once and you found it easier and simple then others and you don't have to spend any money on this..you can also learn it online ..a lot of material is available on the net.
I am using phpLD for my general web directories and phpLB for my bid directory. Now looking at setting up a new bid directory using LBS.
