Notes:

If your email address is or appears to be "corporate" Google will sometimes mark your post as SPAM. It will automatically go into a moderation queue. Rest assured that it will be accepted (assuming it is not really SPAM) and your address will be whitelisted.
As of 8-1-2024 new members will be moderated due to excessive SPAM being generated within 24 hours of signing up by some people. If the first couple of messages are on point then the member will have posting privilege other than Google's ongoing SPAM filtering in which the group moderators will approve or deny.
