Stack Overflow Careers is an innovative new job site for programmers. One thing they have recognized is that participation in open source projects is a great way for potential employers to learn more about a job candidate, and also give developers a new way of differentiating themselves with employers. So they have now announced the ability to automatically incorporate your work on CodePlex projects into your StackOverflow Careers 2.0 profile.
We provide a secure way for StackOverflow to confirm that you are indeed a member of your CodePlex projects, and then display those projects on your profile.
Additionally, since StackOverflow Careers is invitation only, they have provided a mechanism where you can prequalify to join if you are an active developer on CodePlex.
You can check to see if you prequalify here.
