WpfStyles.com (http://www.wpfstyles.com) launched the other day (hooray!). The site lets WPF and Silverlight developers and designers upload their components and share them with the community.
It's all free, so not only are you able to share your components, but you can also download those that other likeminded developers have put up there.
If you have any such components that the community will find useful, throw them up there. I urge you to get behind this resource and show your support.
