One additional change I made that I find works well with a "Master Forum" is to edit your
forumjump template to add a 'quick link' back to your 'master forum.' This is because users may be used to using the forum jump menu to quickly return to the forum they were previously browsing, but if they followed a link from your 'master forum' the forum jump menu will send them back to the listing for the forum the thread is 'really' in.
This link can be used to always return users to the 'master forum' in one click and doesn't take up any room on the page that wouldn't otherwise be wasted.
Edit your
forumjump template...
Find:
Code:
<strong>$vbphrase[forum_jump]</strong><br />
Replace With:
Code:
<strong>$vbphrase[forum_jump]: <a href="/forums/forumdisplay.php?f=1">Jump to Master Forum</a></strong><br />
As always replace the number "1" with the forumid of your master forum. Edit "Jump to Master Forum" and the file path to suit your needs, I personally used "Jump to Off-Topic"
