Some addons are standalone, and are able to run without any additional addons being installed; others can require certain other addons to be installed to work at all, or integrate with other addons to provide additional functionality. Collections of addons that have been put together to form a coherent user interface are sometimes referred to as UIs.

Now he's closing his project yet again. Leaving us all in the dark. Thanks to the few that have to "big men" in the torrent scene. I just hope that someone else comes along that knows what Whoknowsit does and is willing to put up with the egos and the BS in the scene to share the guides we all enjoy. Because all I've seen so far are a bunch of people stealing Whoknowsit's research and the donators' wishes to keep it in THIS scene and safe for THIS SCENE, who don't know what they are doing.
People are never going to learn that sites like Zygor Guides, Dugi, and other premium site actively search out accounts that leak and share the guides and close them down thus cutting off OUR SOURCE OF CURRENT UPDATES! They use methods much like Whoknowsit did by embedding an encrypted tag somewhere with your username or account number so they can trace the leak back to the account. Just as Whoknowsit did.
Since it's like a premium version and it's not modifying game files it gets by somehow. I personally hate Zygor's guides and always have, it's just personal honestly. I understand some people like his guides and have no problem paying for them but I personally hate the idea of charging someone for an addon that - as this post points out - has plenty of bugs in it. These were fixed last week and if I'm paying cash for an addon I want that addon bug free and not causing a hassle and taking my time away when I could be doing a better job without an addon at all.

A few years ago a wow promotion came out that gave you a FoS for leveling a character from 1 to 20. So i started leveling a Horde rogue since i'd never played Horde (and i've played since vanilla), and the fun I had experiencing the "other" side was super fun and nice and I actually saw a lot of cool stuff and actually sorta-kinda got that old "vanilla" feel of exploring things for the first time.
One fairly common issue people have is that older addons they install do not load when they log into the game. This is usually due to the fact that World of Warcraft tags older addons as out of date and aren't automatically loaded unless you tell the game to. This typically happens after a patch, as the game client tends to mark addons as out of date at that point. 

Anyway I will go ahead & download the Twitch app like everyone's saying, but I still need to know whether my in-game addon settings will carry over automatically, or whether they'd return to default same as if they'd all been uninstalled in the curse client then reinstalled from scratch. Because if it's the latter then I will have to take screenshots of the settings on all my toons BEFORE I install the addons thru the Twitch client.
