When writing an HTML document which contains source code, like blogposts, CopySourceAsHtml is a tool of great value. It just takes a couple of clicks to copy source from Visual Studio to your HTML editor. The project did have a somewhat flaky status in VS 2003, in my experience the 1.2 worked well in most of the cases, 1.3 usually gave exceptions when copying. You could not install it in VS2005, posting VS 2005 code took copying it to VS 2003 first.
Today I found a VS 2005 port of CopySourcesAsHTML. Here is a link to an installer with notes on installing. And it works like a charm ! Absolutely recommended.
