Yes I know that they could choose the topic themself, But that is what I don't want to be.
For example
I have the following topics defined:
Traveltips
Materials
When a user is in the Travel area of my site the could see the traveltips (I give the subject in an URL from an page with links) and I would also have the users from that page submit only tips about traveling.
When they are in the materials area of the site the could only see the Material articles and then I would like to have that they can only submit articles about materials.
Thanks again,
Frank
