SourceForge is a Web-based service that offers software developers a centralized online location to control and manage free and open-source software projects. Not a lot of recruiters try to source there. The reason is simple they do not know how. Well to do this without worry you need go no further than into your bag of tricks and pull out an old tried and true tool, a simple search with some extras, and a whole lot of website searching
So to source within Sourceforge you simply need to use a skill known as xraying, like the one below.
site:sourceforge.net/u inurl:profile java
If you run the strings above in google you will get the results below.
