== Preamble ==
Today in a Wikimania 2021 talk page I've tried to write down some reasons against Google Form (but also other stuff as well) plus additional notes in the Wikimedia Forum, both on Meta-wiki.
Some of these discussions against Google Form and similar proprietary tools:
* https://lists.wikimedia.org/pipermail/wikimedia-l/2021-February/096224.html
* https://meta.wikimedia.org/wiki/Talk:Wikimania_2021/Call_for_participation#Please_no_Google_Form
* https://meta.wikimedia.org/wiki/Wikimedia_Forum#Please_no_Google_Form_or_Google_Meet_or_whatever_proprietary_%3A%29_ask_us_how%21
Having said that, even if the problem could be well described, and even if solutions exist (also thanks to our volunteers) it's difficult to help: it's damn easy to diffuse a Google Form but it's damn hard to stop one without a good ready-for-use alternative.
In short, while trying to stop this trend at least by giving greater awareness of the problems ad described in the above discussions, we can try to be pro-active and to play ahead and provide sustainable and credible and simple technologies to everyone.
It seems that the Wikimedia Foundation tried to adopt the free software [[ https://en.wikipedia.org/wiki/LimeSurvey | LimeSurvey ]] in {T109606} but they failed because ~5 years ago LimeSurvey had serious security issues and they already had a contract with a proprietary solution called Qualtrics and as far as I understood they were (sic) happy with that.
In short this Task is related to the infrastructure of [[ https://www.wikimedia.it/ | Wikimedia Italia ]]. Because maybe WMI has more operating margin to quickly deploy a pilot solution and find out how it ends.
Having said that I noticed that [[ https://apps.nextcloud.com/apps/forms | nextCloud Forms ]] and [[ https://apps.sandstorm.io/app/wupmzqk4872vgsye9t9x5dmrdw17mad97dk21jvcm2ph4jataze0 | QuickSurvey ]] are also nice candidates but LimeSurvey is really much more complete and advanced from a lot of points of view (multilingualism, accessibility, responsiveness, completeness of question types, settings, etc.).
Some years ago I saw LimeSurvey adopted in the Politecnico di Torino ([[ https://survey.polito.it/ | source ]]), also in use by the municipality of Torino, to do the most absurd questionnaires (some of them lasted up to 45 minutes (!) like a kind of competition to see who wastes more time and where everyone wins). This gives me the idea that, from a security point of view, it is not stupid to try to install a recent version of LimeSurvey.
Then I was able to further explore the LimeSurvey backend during the [[ https://meta.wikimedia.org/wiki/ItWikiCon/2020/Under_the_hood_of_a_cozy_online_conference#Surveys | surveys for the 2020 Italian wiki conference online ]]. I and my friend @Ferdi2005 were somehow really satisfied by this tool that now we would like to install it on any toaster.

== Proposed solution ==
In short this Task is about ~~toasting~~ ehm installing LimeSurvey in the `wmi-fabula` webserver owned by Wikimedia Italia.
The related documentation will live here:
https://wiki.wikimedia.it/wiki/LimeSurvey
https://wiki.wikimedia.it/wiki/LimeSurvey/Technical_documentation
There was this (actually private - apologies) discussion to pick `survey.wikimedia.it` as cute sub-domain:
https://wiki.wikimedia.it/wiki/Talk:LimeSurvey
We can try to make WMI-LimeSurvey available to all applicants for purposes related to Wikimedia projects, possibly by tracking ideas and not people, for example by collecting feedback and not personal data, unless of course it is the registration form for some live event, or a list of Santa Claus etc.
To avoid to stop the project after a while, to ensure a certain turnover, it could be useful to do regular trainings, starting at least by some of the staff of Wikimedia Italia.
Let's hack with our ~~GForm-killer~~ ehm LimeSurvey.
== Technical documentation ==
Here some technical stuff about our application:
https://wiki.wikimedia.it/wiki/LimeSurvey/Technical_documentation
== Server intervention ==
This was less or more the intervention in the `fabula.wikimedia.it` server to deploy the application:
```
$ ssh boz@fabula.wikimedia.it
$ sudo -i

$ mkdir /var/www/limesurvey
$ cd /var/www/limesurvey

# get rid of temporary stuff
$ rm limesurvey*.zip
# give an useful name
