I noticed that https://we.phorge.it/ has not a footer with a default license, and this is a problem since as default the contents are technically "all rights reserved by respective authors", and so it means that collaboration is not legally enabled.
Proposed footer:
> Public contents are in Creative Commons Attribution-ShareAlike 4.0 (CC-BY-SA) unless otherwise noted.
Assuming the same license of Wikipedia and StackOverflow seems reasonable and implicit.
== How to ==
An Administrator is needed to go here:
https://we.phorge.it/config/edit/ui.footer-items/
And set this:
```
[
{
"name": "Public contents are in Creative Commons Attribution-ShareAlike 4.0 (CC-BY-SA) unless otherwise noted."
}
]
```
