1) As of 8-1-2024 new members will be moderated due to excessive SPAM being generated within 24 hours of signing up by some accounts. If the first couple of messages are on point then the member will have immediate posting privilege on future messages.

2) If you have immediate posting privilege and don't see your message posted then wait 24 hrs or so before reposing as it is probably waiting for moderator approval in which a moderator will address.

3) Google has moderation bots of its own and will delete messages based on certain criteria. Nobody knows why. Try and repost as needed.
