> [@mynoxin](#): > > Now I understand… I made some test-postings and he did not use “[uebergabe@community.uebergabe.de](mailto:uebergabe@community.uebergabe.de)”, it used “[christian@community.uebergabe.de](mailto:christian@community.uebergabe.de)” to post it. But I never created this Actor on Discourse. That is expected if the “Full Post” setting is on (which it must be in your case). The content is posted under the name of the user’s Actor (i.e. you in this case). If you want to post under the name of the category actor you should use “First Post”.

If you’re not sure what this means, head on over to the [Discourse ActivityPub Plugin](https://meta.discourse.org/t/activitypub-plugin/266794) topic first. Instructions To publish to Mastodon: [Set up an actor](https://meta.discourse.org/t/how-to-set-up-an-activitypub-actor/314578) for the Category or Tag you want to publish content to Mastodon. Copy the “handle” of the Actor. Look up the handle on Mastodon and follow it. [note] mar… --- _[View the full topic](https://meta.discourse.org/t/activitypub-plugin/266794)._
