Hello, and welcome to SourceWatch and its Congresspedia project. I'm Avelino Maestas, the assistant managing editor of Congresspedia. Thanks so much for your additions to Ron Paul's page - that was a good catch, as you filtered some opinionated information but left the sourced facts intact. We're always on the lookout for citizen-editors that know where to draw that line, and we're really happy that you stepped up.
I've done a little more tweaking in that Environmental Record section of Paul's page, and left some comments about it here.
I'd really encourage you to keep making changes and working in the wiki, since you've shown an obvious aptitude. If you're looking for some light editing, people are participating in a project to record each member of Congress' vote on recent controversial issues. The Congresspedia staff wrote up some great summaries of the votes and you just have to look up how any member voted and fill in some blanks. Full details are here.
