You were probably redirected here after clicking on neoncastle.net/. Neon Castle, an obsolete forum lasting from August 2018 to December 2019 formerly dedicated to discussing media, has multiple successors encapsulating the heart of the community:
YTPMania is a thriving content creator-oriented community — the current community hub for YouTube Poop and other forms of creative media-editing, and the successor to the YouChew forums. The YTPMania forums are home to various features, such as the tennis café (a subforum for the thriving YouTube Poop tennis community) and Wikimania, along with exciting expansions planned, including a CSS redesign and a return of the articles section.
Angery Dome, formerly the server for Neon Castle, is a server for old acquiantances to reconnect. The server was originally launched by and is once again under the ownership of renowned YouTube Poop veteran Mari.
The Outpost is a Minecraft gaming server for the YouChew community. This link leads to its Discord group, where you can see the status of the game server and interact with other players before you hop in.
The Chewiki archive hosts over thirteen years of collaborative content detailing the interests of the YouTube Poop and the YouChew communities. Tentative plans are in place for a spiritual successor to the Chewiki — you won't want to miss it! Or maybe you will; your choice.
