Ok, here's the replacement stylesheet I made for the forum:
https://www.sideshowcollectors.com/...To-override-board-colors-text-size-and-layout
Extensions are available for most browsers to allow easily overriding styles on a per-site basis - they're mentioned in the post.
Post background has been changed to light grey - easy to change to anything you want
All red bars have been made a muted blue - easy to change with a quick search/replace
Forum width is now resizable with a minimum width of 1000 pixels. (previously fixed at 1344 pixels or so)
Post bars have been reduced in thickness
Most fonts have been increased in size, including quick post text
A few instances of incorrect fonts have been replaced with the correct "Leto" forum font
Huge premium and moderator banners have been shrunk dramatically and placed on a single line
Reduced spacing between lines on user stats under avatar
Removed the underlines under those same user stats
