vBulletin Manual - Modifying Forum Permissions

As stated above, if you wish to set a user groups' options for the whole of the bulletin board, you can modify the user group directly. If you would prefer to configure certain option differently for certain forums, you can set up custom forum permissions.

Click on the Modify Forums link (below the User Groups and Permissions) section of the vBulletin control panel. The following screen will appear:

From this screen, it's possible to set up custom permissions for each user group on a forum-by-forum basis. In addition, you can see at a glance which forums have already had custom permissions enabled, as per the key at the top of the screen. In this case, we can see that the Registered user group has been configured with customised permissions for the Announcements Discussions forum.

To set up a new (or edit an existing) custom configuration, click on the Edit link adjacent to the relevant user group. Clicking on the Registered user group underneath the Announcements Discussions forum will cause the following form to appear:

From here, you can choose to use the default user group options for this forum permission (by clicking on the Use usergroup default option) or you can opt to Use custom settings for this forum. You can set the following options:

Can view forum - select yes to allow the users in this group from viewing this forum.
Can search - select yes to allow the users in this group to search this forum.
Can use 'email to friend' feature - select yes to allow users in this group to forward threads started in this forum using the send to friend feature.
Can post new threads - select yes to allow the users in this group to start new threads in this forum.
Can post polls - select yes to allow the users in this group to post polls in this forum.
Can vote on polls - select yes to allow the users in this group to vote on polls posted in this forum.
Can post attachments - select yes to allow the users to post file attachments in this forum.
Can move own threads to other forums - select yes to allow a user in this group to move threads that he/she started to another forum.
Can open / close own threads - select yes to allow a user in this group to open/close threads that he/she started.
Can delete own threads - select yes to allow a user in this group to delete an entire thread that he/she started by deleting the first (original) post/message.
Can reply to own threads - select yes to allow a user in this group to reply to threads that he/she started.
Can reply to other's threads - select yes to allow a user in this group to reply to threads started by other users.
Can view others' threads - select yes to allow a user in this group to view threads posted by all other users.
Can edit own posts - select yes to allow a user in this group to edit his/her own posts/messages.
Can delete own posts and threads - select yes to allow a user in this group to delete his/her own posts/messages.

As a practical example, please take another look at the screenshot above. In this example, the administator has turned off the Can post new threads permission for the Registered user group in the Announcements Discussions forum. This will prevent all standard users from posting new messages in this particular forum.

Note:

All sub-forums will automatically inherit custom permissions from their parent forum. Custom settings that have been inherited will be formatted in blue text on the modify forums screen.
