[julia-users] Want to contribute to Julia

[cormullion]

If you're still in learning_julia mode, you could help out by checking the 
Julia wikibook (https://en.wikibooks.org/wiki/Introducing_Julia) for 0.5 
compatibility. I've been through it once to update some of the more obvious 
changes and deprecations —  but "you gotta catch em all", as they say!
