There are two main reasons why this guide has been published. I have had to limit mobile bandwidth consumption on 3G connection and to get rid of Git and Ruby issues. Mixing them up with Windows command line is a bit quirky.
Linux and other *nix users should skip it and go with your official guide. I have tested it on a local computer with Fedora 21 Server and it is really easy to reproduce. But on Windows it is not.
And you do not need to change so many firewall settings for cmd.exe, ssh.exe and similar processes. Using web-based OpenShift tools is also much easier for beginners.
We have prepared a new guide for users with rhc and git tools.
I hope it can be used by those who only installed PHP forum scripts.
@gvimlan You can listen to the filter:user.updateProfile hook
and restrict email changing.
UPD: You see that conditional statement, right?
You need to just always make it = null; inside your listener, that's it.
Heh, evidently I stand corrected about DO and NodeBB. Used DO stuff early on (but not for NodeBB). They then became very popular and I saw significant increases in cpu usage without any commensurate increases in load. Boosted a couple droplets up a notch. Didn't do much. Spun up a virgin node and saw cpu loads into 2.x to low 3.x's just idling on my ssh connection. I bailed to a different provider and have not checked in with them in years. Maybe a scale/infrastructure growing too fast issue?
In any case, good that you can get it sorted for minimal costs.
