So here's the current suspect list. If I left something else just add it in. No matter the suggestion, all will be added in for fairness
Nixie (tube) November
Norman (Rockwell) November
NSA November :ph34r:
New Old Stock November
And you won't believe the amount of times 90's Nov was mentioned as being too vague...
Which brings me to a suggestion - instead of simply doing a tally, perhaps show some real commitment to the theme. When you vote, perhaps you can write a bit about why you think the theme you chose was a good one, how you would approach it, what visual element/imagery would you focus on, how you would have it so that there remains a distinctive theme among all of the members, etc. Instead of merely voting this would encourage thinking ahead and seeing whether or not it would really work as a theme. I stress the word theme because this really is important.
I can't add a poll, so I'll just bump this every 15 posts, template for bookkeeping.
