@lightweight #ContributorsWelcome! One way anyone can help is with research, adding new projects to the relevant pages on our wiki, and updating them on the basis of your testing:
https://gitlab.com/fediverse/fediverse.gitlab.io/wikis/
Eg X now successfully federates over #ActivityPub, or Y is adding support for #Diaspora protocols. As the fediverse grows and evolves, this becomes a bigger and bigger job.
