About 120 people gave us this information during FOSDEM 2015:

• Email (required)
• Wikimedia username (if they had one)
• Interested in projects (Wikipedia, MediaWiki, Commons...)
• Preferred languages

We had very different profiles (from software developers to Wikipedia fans that have never edited) from different European countries and speaking different languages. We need to get back to them soon, and decide how to follow-up with them.

A generic first email with some pointers, encouraging them to reply if they have more specific requests?

Draft email

You met Wikimedia at FOSDEM...

... and we promised you to write back. We are very grateful that with so many things happening at FOSDEM, you decided to stop in our stand. This is the one and only email that we will send you, unless you want more and reply back.

We have some suggestions for developers and other technical contributors:

• Join the Wikimedia Hackathon in Lyon (23-25 May, travel sponsorship requests by 31 Mach) -- https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2015

• Apply to Google Summer of Code or Outreachy (24-27 March) -- https://www.mediawiki.org/wiki/Google_Summer_of_Code_2015 & https://www.mediawiki.org/wiki/Outreachy/Round_10

• Fix one annoying little bug -- https://www.mediawiki.org/wiki/Annoying_little_bugs

• Learn how to contribute to Wikimedia tech -- https://www.mediawiki.org/wiki/How_to_contribute

We have non-technical suggestions as well:

• Follow our blog and social media channels at https://blog.wikimedia.org/

• If you liked the Wikimedia gear in our stand, check https://shop.wikimedia.org/

• If you want to (re)start editing Wikipedia, check https://en.wikipedia.org/wiki/Wikipedia:Community_portal (or any of the 144 versions in other languages)

• If you want to meet wikimedians face to face, check your closest match at https://wikimediafoundation.org/wiki/Local_chapters and https://meta.wikimedia.org/wiki/Wikimedia_user_groups
