When it comes time to submit your results, if you haven't registered on HWBOT before then you can register thru their home page.
http://www.hwbot.org/
The left hand side of the screen contains all the links you need.
When you have registered, it's time to choose your team. You do this by clicking on "My account" in the Identification box on the left of the page. This should take you to your profile settings page and this is where you can change all your details. Down near the bottom of the page you will find your team settings. Click the Primary team section and you should be presented with a drop down list of teams for you to choose from and you should find Overclock3D Bench Team in there somewhere.
