I am currently running a reseller script and wanted to expand few of the features of my site, such as having something like a search engine submittal or optimization tool. Any ideas???
I don't know of any offhand but whenever I need a script I first go to hotscripts.com or php.resourceindex.com. If they don't have it, it pretty much doesn't exist and you'll have to make it from scratch
if you really want to offer something new, you should do it yourself or hire someone. An existing script woulld not have much impact.
AGREE ! it's much better to write down all the details about the script that you want and then hire (if you cannot do it) someone to do that script. This will be much better for your site visitors to have unique script rather than using some existing one. Usually, it is hard to find a script which has all that you are looking for.
