Link to ModThis mod allows you to convert ability to see a board and ability to enter a board into a true permission - meaning you can deny access to boards.
You are strongly advised to make this change whilst the forum is in maintenance mode. By default, no boards are visible or enterable except to admin!
View board allows the board to be seen on the board index, enter board allows viewing of topics therein. This way you can set up boards that require a higher post count to actually enter, but visible on the board index to see the description.
IMPORTANT: There are currently no plans to build any kind of importer/exporter for this. Meaning that you will have to transfer access manually. However, for many cases this will be pretty painless, since in many cases you will be using the Default board template, for which it's a case of adding view/enter (both) permissions to the main usergroups.This is NOT transferrable to 1.1 (well, it could be rewritten, but I'm not going to do it), and a converter is not being built due to the impracticalities of trying to do it on a generic basis.
To apply this permission to specific boards, you can create a new permissions profile (Admin > Permissions > Edit Profile > the bit at the bottom), assign that profile to the boards you want
