I really love the idea someone put out of having customizable themes for the forum. The main theme would be the off-white, charcoal and blue, but then you could select a film/game/show and that would be your theme. We could all submit and vote for the theme for each film.
I don't have a computer currently, or else I'd throw together a Firefly version. Brown background, goldish lines/letters, and the fwooshy lines the intro had. I'm also sorely lost as to what I'd do for a Zelda theme, but I'm sure I'll come up with something. Captain America's should be swapped in as the default theme for July 4th, along with BTTF on Nov 5 and such.
Finally, I know that a few prop makers will put in maker's marks in a discreet location. It would be fun if we could add this logo next to our mark for props we intend to sell only through the RPF.
