1. On eForum control panel there is an "
access" setting for each board.
2. This depends on the template.
The general way to do it is to open the template's index.php file and put a code like this:
if ($option != 'com_eforum') {
//show left column
}
//show middle column
if ($option != 'com_eforum') {
//show right column
}
