This isn’t the best way to cross-post. You just submitted the link to the post on [email protected] as a new post on [email protected]

Open the original post, then hit this cross-post button:

Then you can select the community to cross-post to. Your new post will then retain the proper cross-posting metadata so others can find the OP more easily. The power of the Fediverse can also be leveraged to cross-post across instances too, which I did with this cross-post of mine.
