hi howard, I changes the links for the references, questions, and slides pages for the Keasling synthetic biology class. The reason is due to Etiquette topic #7, the idea being that for general words (e.g. 'Research') user's should qualify it (e.g. 'Endy:Research') since there can only be one page called 'Research' on the wiki and presumably a lot of people are doing research. Same goes for stuff like 'References'. I used the '/' so it adds little links automatically back to the Keasling class page now (at the top of the pages), which might improve navigation a little as well. Let me know if any of that is a problem.
