-and
-[`#rust-osdev`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-osdev)
-are for game development and operating system development, respectively.
-There's also
-[`#rust-internals`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-internals), which is for discussion of the development of Rust itself.
-
-You can also get help on [Stack
-Overflow](https://stackoverflow.com/questions/tagged/rust). Searching for your
-problem might reveal someone who has asked it before!
-
-There is an active [subreddit](https://reddit.com/r/rust) with lots of
