There is a way of push / pull requests via GitHub. For this you need to have a GitHub account and a local repo. Send me a pull request and I will try to use the GitHub auto-merge feature which is very easy to use. Please note: your branch should be based upon one of my latest commit.
Another solution: Small fixes could be fixed in my local files manually. Open a new issue: https://github.com/fnagel/jquery-ui/issues/new Your name will be included in the commit message.
Please note that I have only a certain amount of time to support this effort and will allocate it the best I can.
There is a problem with jsfiddle (see: https://github.com/jsfiddle/jsfiddle-docs-alpha/issues/95#issuecomment-2645123 ) and CSS files provided by GitHub.
Demo is broken in IE9 because of wrong MIME types. See https://github.com/jsfiddle/jsfiddle-docs-alpha/issues/95 for more info.
Demo css and js files are now cached via my server. Works nice so far. Please use this files only for testing!
