Good work Govi, Based on the experiences of pulling this off in the other cities - you may need to do the following:
1) Collect telephone nos of the people interested and stay in touch with them. PMing, emailing etc can slow this down too much.
2) Meet up often .. even if it is for just 30 mins so that you guys can build up concrete ideas and execute the same
3) Keep the forum updated so that more interested people can jon in the good cause.
Any doubts toh hum log hain na
