We need a compact site to handle mass email processing on an opt-in (double and triple) basis.
The site will send out invitations to join certain interest groups and require the recipient to subscribe / opt-in.
Data collection would need to cover aspects including ip address of subscriber, time/date and other.
This should be a simple site with add-on pages for information. JOOMLA would be best and prefered for admin of actual site as news updates can be boxed and admin simpler than php for users.
Please send us your response and experience, advice is always taken on board.
