[LGM] Feedback form

[Timothée Giet]

Hi,

We added a Feedback form on the website for participants of previous
editions of LGM.
This can help to create a good press-kit, and tell the world how LGM can
be useful.

Please take a few minutes to fill it if you can.

https://libregraphicsmeeting.org/2020/en/feedback.html

or the french version:
https://libregraphicsmeeting.org/2020/fr/temoignage.html

Thanks!

Timothée
