We have a student network of 400+ people. What we do is to wear advertisement t-shirts and promote companies by using student-to-student communication skills in campuses. We use both verbal and nonverbal communication skills.
Its been 4 years and every year, we are re-building our network because some of our team captains are being graduated.
I have built a social network / portal to manage our studen network using NING. I remember I tried NING before but It was too slow and had little functionality at that time. Now I see that it has improved itself.
Please let me know what you think.
