So, if there's no significant unease with this, we can have it ready and live next Tuesday afternoon (after the very welcome Bank Holiday!).
Why not make use of one of the most excellent features of VBulletin? Sub Forums!
Rather than having the layout on a flat hierarchy, lets get some depth into the forums.
Marketing and PR could then have the sub-forums:
SEO
Press Releases
Mail Shots
Other Marketing
Or something like that, with posts being made direct to the Markting and PR forum if a post doesn't fit within the sub-category.
Just an idea.
