Wow that's a long title...
Well that's the question: is it possible to let users create their own terms (categories) and then be the only ones who see them in the content creation form.
I ask this because I want the user to create a basic category and then add content to it. But I don't want other users to be able to add content to categories that they have not created.
So for example I have a category My familly and then I add one node per familly member. It would not make sense if every one that want to add a "familly member" node as other choices that it's own familly (famillies). This example is not the best cause having 'my families' does not need to have so many categories.
Let's say I have a travel site an I want users to create some pages of souvenirs about their trip. I would like the person to submit a new term/category like for example: "my trip in spain". Then the person could add nodes for each city she visited for example. All nodes related to his trip in spain would be in the My trip in spain "category/vocab" , which in return would only be available under her profile, and of course in the Spain, category.
Is this way of letting people adding content a little crazy?
Would it be best if I simply let people tag content and the select the country? Or maybe user nodereference so all nodes related to his/her trip to spain are linked together??
