You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !mildlyinteresting@lemmy.world

This is for strictly mildly interesting material. If it’s too interesting, it doesn’t belong. If it’s not interesting, it doesn’t belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh… what do we know?

Just post some stuff and don’t spam.
