@Dodecahedron during the last forgefriends meeting you said it would be a good idea to call for help. Here is what I could toot. My reach is small but that’s what I can offer 
And maybe others can relay and have a bigger impact.
@aschrijver Do you have suggestions to improve that toot?
@gitea needs your help to implement #ActivityPub 
Browse the task list maintained by @Dodecahedron at #3 - Gitea federation task list - gitea - Gitea: Git with a cup of tea, pick one and help #Gitea move towards #federation. If you are not sure how to help, just reply and someone in the @forgefriends community will guide you.
boost appreciated!
