yes, as @davorak said cultural changes doesn't happen overnight. also, "starting small and expanding - that's a good thought."

we started with events on occasion of global events like celebrating open source day, wiki days or other global happening, getting support from the organizing bodies. they are now performed yearly after we graduated.

don't forget to include geeks from your junior circle. since they will be the one to continue your effort after you graduate. what we will do is convey the message about the geek/community culture, collaboration culture. feeling depressed why other students don't think that way is completely waste of time, get over it.
