Indeed it worked eventually. I was then able to crosspost to offgrid.

Thanks!

Note that i get the following:

Error!

There was an error on the server. Try refreshing your browser. If that doesn't work, come back at a later time. If the problem persists, you can seek help in the Lemmy support community or Lemmy Matrix room.

The server returned this error: FetchError: invalid json response body at http://lemmy:8536/api/v3/post/list?community_name=offgrid%40slrpnk.net&page=1&limit=20&sort=Active&type_=All. This may be useful for admins and developers to diagnose and fix the error

I suppose (hope) that’s an uncommon glitch. I was at least able to subscribe using the search method.

Are there #hashtags on lemmy? Can I follow them? Can I group them?

#Lemmy apparently has no concept of hashtags, but when you write a post it’s still a good idea to write hashtags because kbin & mastodon users can search by hashtag and find your post.
