but I can't figure out how to automate that process
You need browser extension like Stylebot.
My own messageboard tags are causing every post I make (and, by extension, every thread I post in) to exceed the width of my screen.
Would it be possible to have someone change the setting for the style in the .css file for the Paizo messageboards from to ? I can manually instruct my browser to make this change every time it displays one of your pages, so I know it fixes my problem, but I can't figure out how to automate that process, so my browser keeps defaulting to the setting in your .css file that prevents messageboard posts from fitting on my screen.
A thousand times this. The constant horizontal scrolling is making it a pain - almost literally - to follow RPG Superstar. To give the other entrants a fair shake I have to read their entries and your Web design is making this thing that should be a pleasure tiring and annoying. And if I'm saying that as someone who is in the top 16 myself, I can only imagine how much it turns off many of your more casual readers, with less invested in RPGS.
Yeah, I can use third-party add-ons to work around the problem. But I shouldn't have to.
