I'd suggest you check the credits pages in the mangas you like to read. Usually, the scanlation teams will make it known there how you can get in contact with them, like through a website or an email. Each group will have their way, just look for it, and you'll quickly find how to join.
Okay, thanks so much for the tip! ^^
before you join a scan group search up tutorials on how to do it. a cleaner isn’t just about cleaning the original text you might also need to clean sfx and redraw certain scenes. also most scan teams only allow people with experience to join. I’m in one but it’s new so we don’t really care too much about experience so just make sure to ask the scan team you want to join about that since all scan teams are different.
you could also become a typesetter since that’s an easier job too do
I don’t really know where to begin, as I don’t know how to translate I’d probably be best as a cleaner (someone who erases the original text) but even then I don’t know how to clean up or where to contact them. I just want to pitch in because I really admire their hard work and know that they need help!
