Maybe something I can try for the purpose of learning #Rust is setting up a real-time communication channel in #NodeBB (i.e. a socket that the web UI could use to show real-time information, typing indicators, etc). Maybe it's too easy or too hard... I also have an audio processing project I intend on doing in Rust but I haven't managed to get myself to do that yet.
Also, I still want #PikaPods to have NodeBB. It might become affordable for a lot more communities that way! There's a request lodged for it in their feedback thing but there's currently no indication they plan on adding it.
