I've been trying to find a database front end to use in Wordpress and apart from a very complicated Participants Plugin there is nothing else available, I am building a site for a car club (not for profit) and they want to enter the vehile details and current whereabouts of vehicle that have passed through their club dating back to 1926 so it's available to all their members and members of affiliated clubs wordwide. So that's my suggestion, a Wordpress PLugin.
