How to go to forum by forumname?
 

{vb:raw foruminfo.title}

forumdisplay.php?forumname={vb:raw foruminfo.title}

Let's say the forumname name is "A" (id: 2).

How would I access it by URL like

http://yourname.com/forumdisplay.php?forumname=A

Currently, the forum can be accessed by

http://yourname.com/forumdisplay.php?f=2

Thanks.

i know it would require edits to forumdisplay.php to allow a ?forumname=X call (and maybe other files)

Your best bet would be rewriting urls. or if you have vBSEO, customizing the way urls to forums are displayed.
