It all depends if you want to build layouts (or reports) on the join table. Reporting on records with multi-key fields is tough.
Using a checkbox to create/delete records in the join table can be done through script triggers but it is messy. Think of better UI ways to do the same thing if you want to go that way.

Do you have a idea how to make the UI better for this issue. I could make a portal with line items that shows al the 'selected' categories. But i found it nice for the users to see the whole list of categories for a project and select via a box or button which categories this project has got.
Thanks Erolst! That's exactly what i mean. I going to dig in to understand it. Thanks!
