As a web developer (with a data base developer background) I use a lot http://jsfiddle.net/.
Its a great tool to allow developers to share source codes and help to solve problems.
For a long time I wished something similar for SQL Server and this year I found it.

But I don't see it a lot at the community. In special I never read about it here in SSC.
I searched about it and cannot find a simple topic and that's why I'm sharing this finding here.
