Anytime you notice your post is missing you can assume one of two things.
1) The post did not follow Club guidelines and was deleted.
2) The message was posted in an inappropriate forum and was moved the the proper Club. This may be in the Groups Forum which includes Jokes, Poems, Music, Politics, Fun, etc.
All Eliters should really check out the Groups Forum, there are many interesting threads posted there (not to mention some pretty tasty recipes!).
If you have questions about Clubs, please check out Help Topics 1801, 1802, 1803 & 1804. If you have concerns or suggestions, please email me firstname.lastname@example.org
