Welcome to Congresspedia and SourceWatch. As the associate editor of Congresspedia, I try to greet new users and offer any guidance I can to help them get acquainted with the site. We appreciate your correction on the page of Sen. Brownback, and hope that you will continue editing. I checked, however, and Brownback is indeed the senior senator in Kansas. He was elected in mid-1996, while Sen. Roberts was elected in November 1996.
While editing on the site, your best reference is going to be the Congresspedia help page, which links to just about every other help or guideline page you’ll need. Feel free to use my talk page or email me at efullmer AT congresspedia.org if I can be of any assistance.
