Stylebot is really great and super simple. If you know your way around CSS, the edit CSS button at the bottom is what you want. Use inspect element to pull the class name or id and then write away. It's basically like changing the CSS thru inspect element but automatically loads whenever you visit a certain site.

One thing to watch out for is that if you are fucking with the layout of the hubwheel comment title comment, the css is slightly different for the comment page vs the badge page even though the class names are the same. That frustrated me to no end when we were trying to get a semi-responsive version of the site good.

Last note, we're just beginning a major rewrite of the backend and frontend of Hubski. We're aiming for Thanksgiving but you know how that goes. So if you pour hours into changes it's all going to break sometime in the next 6 months. :)

What languages to you typically work in? I've been doing HTML/CSS/JS for a few years and just redesigned my company's site from scratch. I'm more a designer than developer but it looks like I'm going to get to know some real programming languages for this rewrite which is really, really exiciting!
