Thread:Project:Forum/Common.css ~ Where is it?

I guess I am dumber than a rock...I can't find the file common.css so I can do changes to it even though I have basically searched for a day and a half. Can someone please tell me where the file is located. I am using the current version 1.16.2 – 2011-02-01 and the Vector skin.

please email me with the info codi727@gmail.com

I appreciate any help you can give me.

Thanks
