Yes, you can do this from almost anywhere in the Fediverse. As Mastodon does not recognise headings, the first paragraph becomes the heading. This means that it looks better on Lemmy if you put the community tag at the end of the post and start with a content-related introduction.

hmm, the titles are a bit broken.

Sort of, it's because a lot of microblogging software doesn't have the same post format with title/post body. The current workaround for microblog to Lemmy and similar is to format it like this:

first line title

second or more lines post body

@communityname@site.name

#hashtags if desired

I will keep this in mind, thanks!

I would recommand however not to mention it on the first line of the toot. It breaks the title.

@pseudo@jlai.lu Yeah, found that out. Thanks anyway!

I once made a small guide to this here: 🚀 A little guide on how to communicate with Lemmy from Mastodon, Friendica, Hubzilla, Sharkey etc

You can also follow a community from mstodon but it shows all the replies from all posts and it's very messy.

This is the case with all content (posts + replies) on Mastodon, as it appears separately in the timeline. In this case, it has nothing to do with Lemmy.
