Organizing SDMCET Alumni World and making it accessible

Organizing SDMCET alumni world and making it accessible to all interested is a challenging job. Benefits of such an organized alumni world is there all: alumni, current students, and more importantly to institution itself.
There have been many efforts towards this - creating Google Groups, Facebook groups and each have resulted in becoming a subset of big alumni population and an isolated world in itself.

But I want to give a try and work towards bringing all SDMCET alumni together. You may been requested to contribute your ideas on how to approach this and take this further.
