I found a question on logo design. However I didn't find any on the rest of the look and feel of the final site.
I created a question to contain suggestions of what the theme for the site should be. Suggestions for the button styles, colour theme and things go here. Quoting from The 7 Essential Meta Questions "We have designers on staff to come up with site designs but, if an idea stemming from the community stands out as exceptional, we are happy to use it." So we can suggest if we want.
Basically, what do we want our new rpg stack exchange site to look like?
