I'd like to add functionality (a tab) to the my account page (/user).
In that tab i'd like to provide the users to add content of a specific content_type, only one (node_limit)
Once created I'd like to keep the tab and then the user can change the node there.
For example a car site, user can add one car in their my account (with description/fotos etc...), if changes are made to the car changes can be made trough the my account page..
No clue to get this started, probably some hinting on modules will do to get me started
THX a lot
