I want to make a matrimonial which will have only basic features.
Registration option and edit profile option.
8-10 profile fields, with few compulsory fields.
Option to create custom fields.
It should auto delete IDs after 3 months. Enable/Disable option.
Paypal 3$ fees for registration.
Admin must have the right to reject a registration. A moderation system.
You could use wordpress/joomla with free modules/plugins, or you could write your own code.
There is a Genie Matrimony plugin and S2 Members plugin for Wordpress, not sure if these have all that I need.
