If you wanted to make a text post on #Lemmy from Mastodon, one key thing to remember is that the content warning is not the title of the post. The first line of your post is their title. If you wanted to write in the body of a post for example, you would drop down two lines. Like this.
This text will become the body of the post on Lemmy because it is on a separate line from the title line above.
The first line of your Mastodon/Hometown/Glitch post is the title of their post. The second line, after a line break or paragraph break, will be the body of the post.
I don’t know if you can post to #KBin yet from Hometown or Mastodon yet but I hope that will get added soon! #FediTips
