A number of options are configurable in the forum module. Most are in the CMS and can be customized on a per forum holder basis which are configurable from the forum holder page.
An example of options which are configurable in the CMS include
- Show In Categories - Group multiple forums into a 'category'. Eg Modules might be a category and Ecommerce, Forum would be forums in that category
- Display Signatures - Allow people to attach signatures to their posts
- Forbidden Words - List of words which will be removed from posts
- Viewers - set who can view this forum
- Posters - set who can post to this forum
