These are the items you need to take care of when organizing a GNU/Linux install fest
- Find a hall that can host the event, try in colleges, schools, libraries, IT companies that are generally supportive of Free Software
- Form a core group of limited members, create a check list and assign duties to each (something like collaborators cooperative will be effective)
- Decide a date soon so people can plan to attend
- Create an RSVP page for people to register. You could use loomio's 'Check' poll (using proprietary services like Google Forms are discouraged)
- Add RSVP link to your website or fsci.org.in/events
- Make a poster with RSVP link and contact phone number
- Add event details to Debian Wiki, if it is a debian release party.
- Announce it on mailing lists (your local user group list and also neighboring districts' user groups). You can find a list of user groups across India at https://fsci.org.in
- Send a press release to news papers, TV, Radio etc
- Make stickers of Free Software projects
- Make sure you have enough bootable pen drives, DVDs etc
- Have blank DVDs for people who want to take images
- Arrange demo of the different GNU/Linux distributions
- Try sponsorship to cover expenses like disks, stickers, etc
- Introduce Riot app to them and tell them to join #GNULinuxLovers channel for continued tech support
- Send report of the event to all news papers with photos on the same day of the event
- Post photos and report on website, mailing list and social media (consider Diaspora and Mastodon as well)
