This site is really responsive and looks nice, has lots of good features etc... well done to the devs who created it... I know some Rust and could probably help out, I will have a look at the tickets and see if I can find time to explore the source code... thanks for the raising this up, I am sure others like me will find this and want to join the battle... being open source and community owned, I think it deserves contributions from users who are able to (and donations for those who still want to help but can't contribute code).
EDIT: wow the code is very easy to follow! Highly recommend having a look if you know some Rust or want to practice Rust :)
