Other collaborative methods, some enabled by tools that we've set a bit aside this year:
* local git repository vs larger git archive: https://gitlab.com/relearn && https://gitlab.constantvzw.org/relearn
* social shell http://relearn.be/2015/etherdump/Social_shell.html
* ether dump
* message boards
Baseline is common documentation
What are your preferred tools of trade when it comes to collaboration?
More xmpp bots?
maybe together with documentation for internal/external use, also what we leave for poortbegouw ;)
