3. Administration


How do I add a new Forum to a Category?

Forum categories are top-level groups of forums. An administrator can create categories, add and remove forums from a category and remove categories.

To add a category, from the Administrator's control panel, access the Forum Management page and click on the Add new Category link near the top of the page to load the category creation screen. A category simply has a name and a description. Use a short enough description to give forum users a concise understanding of the types of forums they will expect to find in the category.


Should I associate the Admin section of the forum with an easy to identify URL?

It is up to you, but by default, we suggest not doing this so as to minimize users attempts to access the administration site.


Can I restrict certain users to specific Forums?

That feature is not currently supported. See the TODO list for the intended inclusion of this capability

If you are building mvnForum, just change the file to the appropriate values.

If you want to change the default displayed language in the binary distribution package, just copy all the files from the subfolder of webapp\mvnplugin\mvnforum\user that contains your preferred language to the webapp\mvnplugin\mvnforum\user. For example, if you want to change the default language to Vietnamese, just copy all files from folder webapp\mvnplugin\mvnforum\user\vi to folder webapp\mvnplugin\mvnforum\user
