In my university, we the students set up a wiki for our course where we have added links to resources (lecturer's homepages and misc.) and some summarised notes on courses (along with timeless quotes from lecturers!). Personally, I find it extremely handy and would recc. it and although it can be hard to coax participation at times, our wiki is passively quite active (pretty much everyone in our year refers to it, naturally peaking around exam time). http://www.maths.tcd.ie/~mathsoc/wiki/Main_Page http://www.maths.tcd.ie/~mathsoc/wiki/Main_Page
