i'am interesed in a classified ads directory (with 3 pictures by post) with banner exchange (if someone post his profil or website, he need to put our banner in his/her website).
You can find an example here [url removed, login to view]
In this directory it will be good to implement a web promotion fonctionality like "PHP Submit".
Needed admin control panel to valid new subscription.
Thanks for you interest.
