Now, I know that Vizzed has their own server, but I feel like I need to highlight another server which is currently only invite only, and while I'm not a part of it, there are quite a few popular YouTubers Who are on it, known as Hermitcraft. It is currently in its fifth season after a very recent world reset, and features many different Minecraft players, including redstone constructors like Mumbo Jumbo - who is the main person I follow.
They do have a homepage which not only allows you to see the most recent videos, but also allows you to download the worlds at the end of each season of Hermitcraft, at http://hermitcraft.com - and a good place to get an overview of the events is through the Hermitcraft Recap channels.

Anyway, here, you are free to discuss Hermitcraft episodes both new and old, including any spoon moments which Mumbo ends up in, the crazy builds some of them make, and... Well, anything Hermitcraft related.

Oh my word this is bonkers, somebody else that watch the hermits other than me!
I only follow iskall's episode so far, and he's doing a really interesting base concept in season 5, if u didn't saw his episodes, I recommended you to do so.
I used to follow Mumbo and Rendog's stuff, but they got me bored in season 4 so i kinda stopped, iskall only lol

Well, I mainly follow Mumbo, but I do sometimes check on Tango and a few others.

But I think I will have a look at that hermit and what they are doing.
