@Codejet I'm making kinda similar plugin right now.

The plugin's goal is to show only one badge with a "most high priority".

Let's say a user is in three groups:
"Officer" (group's weight: 60)
"Recruiter" (group's weight: 55)
"Regular" (group's weight: 50)

Regardless of what was choosen in UserSettings as a badge, only "Officer" badge will be shown, 'cuz that group has higher priority than others.

And the question "Why users are in multiple groups?": Because of ability to manage those groups' membership.

@Codejet said:

what code would I add to the template if I wanted at least 2 badge's displayed in my posts.

You need to make and register a new template helper, for both clientside & serversde, and execute some magic inside.
I can help you via Teamviewer, if you please ^.^

How many instances can I install on 512Mb RAM digitalocean droplet?

One at least

If you'll use Redis, and your forums will have less than 100k messages each, probably two
If you'll use Mongo, in the same circumstances, maybe even three instances

However, I'd recommend you to use 512MB droplet for each instance

@frissdiegurke open the console in browser and type config['theme:id']

@Popatop15 I'm sorry, but it's near to impossible. Take a good look at those examples https://github.com/NodeBB/NodeBB/tree/master/src/database

The differences between MySQL and any noSQL databases are huge.

NodeBB architecture was designed with Redis in mind. Redis it's not even a database at all, it's an advanced key-value store (completely noSQL). So, it's relatively easy to make a driver for a noSQL database, like MongoDB. But it would be way too hard to implement that kind of a driver for a relational database, like MySQL.

Just to be clear - even though, strictly speaking, it is possible to make the driver, NodeBB won't be working good with it anyway.

Personally I'd suggest you to spend some time to learn how to work with MongoDB, if you still unfamiliar with it. MongoDB is very popular nowadays and working with it is much easier than with anySQL database. If you're an expirienced dev, you can become a ninja in just one week.
Then, you'll be able to make an effective bridge between Mongo and MySQL parts of your applications.

p.s. Just in case, I want to mention that everything is possible.

I need support when creating a plug-in, as this will be my first plugin NodeBB and he, as I understand it, will not be easy.

We may have a talk about NodeBB and its plugins in Russian over VoIP (Teamspeak?) if you want to. I can point you some pitfalls, and even some best practices in plugin development

Already in 2015. Maybe again in 2017?

How can I vote for NodeBB on the CMS Critic site? Please, explain like I'm five.

I just wonder, whether someone is interested in a guide of automatic incremental backing up NodeBB using rsnapshot on Linux-based servers? I mean not a tool, but a guide only. Because I have no intention yet to make neither the tool nor to contribute to the nodebb-backup tool.

And if I'll make the guide someday, it probably will be not for complete newbies, but for those who's able to (at least):

1. use terminal
2. completely understand what chown and chmod commands are for, and what * * * * * in cronejobs mean

p.s. When you're using rsnapshot, there is almost no difference which database you're using, Redis or MongoDB.

to display localized date strings

Sorry, I've noticed it just now >.<

Okay, AFAIK, you always, on any page, can do

$('span.timeago').timeago()

And all spans will be translated in appropriate language, BUT
I guess, you actually don't even have to do this! (unless you won't load some content dynamically, not via ajaxify.go())

Because behind of every click on a link, there sits ajaxify.go() that, after each page loading, casts app.processPage() that already includes $('span.timeago').timeago()

Just in case

Probably it isn't what you expected to get as an answer

@MJ CSS? Nah. Just execute some JS
For example:

$(window).on('action:widgets.loaded', function () {
	$('li[component="categories/category"]')
	.add('li[component="category/topic"]')
	.find('.stats > small')
	.each(function (i, el) {
		var
			$small = $(el),
			text = $small.text(),
			$icon,
			iconClass

		if (text === 'Topics')
			iconClass = 'fa-group'
		else if (text === 'Posts')
			iconClass = 'fa-group'
		else if (text === 'Views')
			iconClass = 'fa-group'
		else
			return

		$icon = $('<i class="fa fa-fw ' + iconClass + '"></i>')
		$small.replaceWith($icon)
	})
});

P.S. Actually, the best way to change something in a theme - is to fork the theme and make whatever changes you want in your own repository. But you'll have to keep track of any new changes from the original theme repository, resolve merge conflicts, etc. This way is a hard way. The example I've provided above is the easy one.

That's a weird one.

Truly.
The weirdness is in fact the error comes randomly O_o
Steps to reproduce: continue pressing a "Page Reload Button" (Ctrl + R?), one per 10-20 attempts you'll catch the error. No matter what page you are on, even ACP.

And not only the one error, some others too

@Rex-Huang I faced the same error when I've made fork of the plugin.
I found a way, how to get it work... Maybe it may be useful for you.
