I’ve just started using Soulseek and it’s great. I want to make sure that I’m being a good neighbour on it - do I need to do anything to ensure that my files are available for others to download? And do I need to structure directories e.g Artist name > Album name or does it work off metadata?


You probably have to set somewhere which folder(s) you want to be discoverable.
Regarding directory structure, Soulseek search only uses file names as far as I as know. So having a consistent naming structure certainly helps. Some tools like the fantastic MusicBrainz Picard might help!

The search uses filenames and parent folders.
Structured folders also helps since you can download whatever folder a specific song is in so typically the folder would be the album title with the artist one level higher.
