So I would be in need of a plugin for my forum where users an select a language from a dropdown when they create a post. That language is then added to the post in the overview. This is because we are a bilingual forum and it would make it easier for people to flag threads in a certain language. I haven't found anything like that but I can see this being useful so eventually I'd like to try my hand at it.
Now I have some mediocre coding skills but I have absolutely no overview over the way Vanilla Forum is structured. Maybe someone here has some pointers on where to start? Good tutorials? Relevant links? etc.
