Is it possible to change the rules of this site? I have some ideas as to how to improve this website and wanted to know whether I can make any contributions to the way the site operates.
Yes and no. We are able to change some aspects of this site as long as they adhere to the basic goals outlined for this site as it was created, and as long as they conform to StackExchange's philosophies in how they want their Q&A sites to be formatted.
So for example we can modify the kind of questions we accept in the Q&A format, how strict we need to be with citing/referencing, how much original research is acceptible, etc., but we can't turn this site into a forum. Questions need to be questions, and they need to have real answers.
If you have an idea, by all means share it with us here. We will tell you on a case by case basis whether it is allowed or feasible, and other members of the community can chime in as well on how they feel about it.
