There were people from 30 countries at the Berlin hackathon this year.
It'd be cool if, by this time next year, there were 30 get-togethers to
help MediaWiki administrators swap tips and talk about what's happening
in MediaWiki development.
You can do it. You can do a case study of "ways to improve your
MediaWiki installation" at your local system administrators' or PHP
meetup. You can look for interested techies near you who want a
"helpathon." We can help.
