I don't have an install up and running at the moment, but this setting does appear to be configurable:

User.sendInvitationEmail = function (uid, email, callback) {
		callback = callback || function () {};

		var token = utils.generateUUID();
		var registerLink = nconf.get('url') + '/register?token=' + token + '&email=' + encodeURIComponent(email);

		var expireIn = (parseInt(meta.config.inviteExpiration, 10) || 1) * 86400000;

src/views/admin/settings/user.tpl: <input type="number" class="form-control" data-field="inviteExpiration" placeholder="1">

So I'd look for it somewhere in admin user settings.

Not to be rude/judgemental, but you will need some technical understanding to successfully deploy and maintain your own NodeBB installation.

The official docs are a great place to start, but they won't hand-hold you through registering a domain, configuring DNS, etc.

If you don't want to tackle that, NodeBB have paid plans that they will manage for you.

@pitaj Thanks, will have a play later. I haven't actually installed it yet, was just having a dig around the code.

@alexsir Yep, I guess that's the port NodeBB is configured to listen on my default. At the end of that guide, there's a link to another guide that explains how to configure nginx as a proxy - which would allow you to either configure a domain to point to your NodeBB process, and/or omit the port from the URL.

I haven't applied your CSS to my own install, so I haven't tested your specific code, but; if you want different behaviour for different medias (desktop/mobile), you can play with media queries.

e.g.

/* Smartphones */
@media (min-width:320px)  {
  body {
    font-family: "Courier New", Courier, monospace;
    color: #ffffff;
    background-color: rgba(0,0,0,0);
  }

  html {
    background: url(https://9854.moe/assets/uploads/system/background.png) no-repeat center center fixed;
    background-size: cover;
    background-color: #000;
  }
}

/* Desktop */
@media (min-width:1281px) {
  body {
    font-family: "Courier New", Courier, monospace;
    color: #ffffff;
    background: url(https://9854.moe/assets/uploads/system/background.png) no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
  }
}

May be faster for you to figure out the correct credentials using the CLI:

mongo --username <yourusername> --password <yourpass>

Also worth attempting to connect with no credentials, on the off-chance you haven't correctly enabled authentication.

mongo

If you can't figure out the correct credentials, you can set up another set with this official doc.
