How to get different special pages/links for different user roles
We're considering using multiple categories with permissions set by the categories to manage multiple forums. Most of the users will be in one category or another with few of them in multiple categories ("forums"). Vanilla seems to support this out of the box, and together with some plugins (e.g. hide categories) it looks like a workable solution.
Most of the look and feel would be similar but we'd like to have some of the menu options dependent on the categories. Since the user roles permissions define which categories they have access to, I'd think that the menu options will be based on the user roles (most will only have access to one category). This way, we're thinking that using one of the several plugins that offer "extra pages" we can have different privacy pages, about pages, and so forth on a per category/forum basis.
Any suggestions as to whether any plugins already do that or are so close to what we need that someone can offer a suggestion on how to get there?
Other advice on managing multiple forums through category "isolation" would be welcome.
