Okay, sorry in advance that this is a complex thingy I'm asking for, but here goes.
I have a site that uses one theme for browsers, a different theme for mobile (via the excellent WPMS Mobile Edition). I have Vanilla forums installed and embedded at my WP site. I would really like to modify the mobile theme to redirect the Forum page (and ONLY the Forum page) to the Vanilla Forum URL.
The problem is there's already one redirection from the regular theme to the mobile via the WPMS Mobile Edition.
