I've made an open source tool for scheduling posts to Lemmy, you can find it at https://schedule.lemmings.world. It can be used by users from any instance and it can be self-hosted if you wish so!

Changes since the last time I posted about it:

• you can now login with 2FA enabled
• you can schedule pin and unpin of posts in a community if you're the mod
• you can schedule pin and unpin of posts in an instance if you're the admin
• when creating a post, you can choose to pin it to the community (if you're a mod)
• you can choose the language of your posts
• an official support community has been created at [email protected]
• you can post the same post into multiple communities easily, just select the communities and multiple scheduled posts will be created

Let me know what you think!
