I like project announcements under Main.
I never look at the restorations, but if it were under project announcements I probably would.
I'd be more worried about getting rid of a row than a column, so it takes up less of the page.
My $.02
Row 1 (core stuff):
Main
Project Announcements
Restorations
Pinball
Arcade Misc
Row 2 (cab building stuff):
Monitor/Video
Woodworking
Artwork
Driving & Racing
Automated Projects
Row 3 (starting to break down
):
Consoles
Merit/JVL
Audio/Jukebox/MP3
Project Arcade
Raspberry Pi & Dev Board
Row 4:
Software
GroovyMAME
Front End Support (separate subforums for Mala, Maximus, ...maybe add Hyperspin if someone wants to manage it)
Linux
Dos/WinCab (I don't even know what this is)
Row 5:
controls.dat
(whatever I missed or don't combine something)
Forum Discussion
Wiki Discussion
Old Boards (contains both old boards & old archives)
Row 6:
B/S/T
Retail Vendors
Reviews
P&R
Everything Else
EDIT: Maybe put the raspberry pi forum in column 2 and driving cab by consoles in column 3?
I'm ok wherever the driving cab forum ends up....or where anything ends up for that matter.
I just think more traffic can be generated by organizing them more strategically.
