SquidTL allows proxy administrators to manage proxy users: define how much time users can spend on a specific Web site, block sites, limit total time users can spend on the Web daily, and watch users' activity. For example, you can limit the use of Facebook or other social networks with per-user rules or IP. It has a small memory footprint and very fast execution. Management can be done with a smart Web-based administration GUI.
iDem is a Web application that lets groups vote and decide on any proposal. Organized hierarchically, this system was created to help groups vote on any proposal made by anyone. Proposals can also be restricted to only certain users. Every proposal has a defined lifetime, and users are encouraged to vote.
