Nasscom Product Conclave 2011: What tools did the organizers use?

The recently concluded Nasscom Product Conclave 2011 in Bangalore was a vibrant conference to attend. I got involved from August 31 when I was asked to put together a session. From that very day, I saw how well organized the Nasscom team (plus the volunteers) were.

A few tools that were used for the conference,

1. Deskaway.com (paid product) for project management
2. ZipDial (paid, don’t bother to look for a free version): After each session, delegates could give their feedback on the session (polling) by giving a missed call.
3. E-Campaigner (paid) for mailing newsletters.
4. Qontext (paid) & Google Docs (free) for collaboration of sharing of documents and various things.
5. Insighto (paid) for collecting & analyzing surveys from delegates over the web.
6. DoAttend (free for free events, nominal fee for paid events) for registrations. They allow credit card payments.
7. slideshare.net (free) for hosting all presentations.
8. issuu.com (free) for brochures, program guide, etc. See NPC guide for a sample.
9. Sched.org (paid) for the entire scheduling of the sessions. Delegates could create an account and select the sessions they would want to attend and print out the schedule.
10. Vangal (paid) for generating the social media metrics for the conference (from Twitter).
11. Flickr (free) for hosting all photographs.
12. Youtube (free) for hosting all event videos.

Please feel free to suggest any new tools one could consider for organizing an event (for the Indian audience please).
