If you're using pm2 loader.js, you should use the restart button in the ACP to restart NodeBB...
I was dag nabbit.
(... or ideally, don't use PM2 at all, since the loader supercedes it. Just: ./nodebb start)
But I like to use pm2 because I use it for all of my other task management needs. Where in the code would it be?
The due date for 0.5x is mid June-ish, although we have a ton of cool things in the works aside from this so it might be pushed a week or so beyond that. Can give you a better estimate once we start rolling stuff out, @baris already has the initial version out for the tag system for example
