### Spaces
There's no IRC equivalent to Spaces (I'll probably write a spec for it since it's widely used elsewhere). Since they are just regular rooms, they show up in IRC as just regular rooms. You aren't supposed to send messages to them, once I implement mode handling I'll use `+m` to disallow sending.
### Client overload
If you're in a ton of channels, or several big ones, your IRC client/CPU might melt slightly on initial sync. I'm working on a "lazy-loading" channel list to fix that. Joining `#matrix:matrix.org` using WeeChat pegs a CPU core for a good 45 seconds.
### Highlighting users
In order to highlight users, you need to prefix their nick with an `@`, so `@emerson: hi`. Reflection automatically expands this to the user's MXID, so even though it's annoying, it's needed to stop inadvertent highlights for now.
