There's a few IRC games running. TriviaBot runs in #trivia. This bot asks simple questions, and it keeps a daily, weekly, and monthly score (As well as all-time scores). No need to register.
idlerpg is an role playing game, probably unlike any other you've played. You advance by doing *nothing*! That's right, the longer you idle in the channel, the better your progress. You get penalized for chattng, nick changes, etc. It's available in #idlerpg
The tildeverse has it's own radio station! You can join in with the fanbase in IRC in #tilderadio, and listen in at https://tilderadio.org. People run shows, and often interact with the audience in IRC.
Most tildeverse servers also host content via the gopher protocol. You can access this using ```lynx``` on the shell of most tildeverse servers, or by using the tildeverse [gopher proxy](https://gopher.tildeverse.org/). Check it out, there's dozens of us! Dozens!
The tildeverse also has our own search engine, available at (https://search.tildeverse.org). There is a Firefox plugin available in the Firefox app store that will set your browser to use it as the default search engine as well, written by Your's Truly (ubergeek).
Way back when, if you wanted to transfer files, or send email, you used the UUCP protocol (Unix-Unix Copy Protocol). Some tildeverse servers have this set up today. You can join in #uucp for more details. Praetor is wrangling that project.
The tildeverse also has their own top-level domain name system: .tilde. In order to request a domain name there, you can go to #.tilde in chat, or do a pull request to the repo at https://tildegit.org/.tilde/.tilde.
