If you have a new post or newly edited post that is missing it is likely in the spam quarantine.
Please do not resubmit a duplicate post.
The quarantine is regularly monitored, but to have the post restored quickly you can post a thread here in the Technical Help forum and the missing post will be retrieved for you. You can also reach out to any moderator via PM if you would prefer.
Please note that if you attempt to copy-and-paste the text from a missing/quarantined post into a new post often the new post will go into the spam quarantine as well (which then must also be retrieved).
As always, feel free to reach out to any of the moderators if you have any questions.
