For the uninitiated, new members and members who lurk in the background who decide to post for the first time, your postings will not appear immediately and that is by design.
These delayed postings apply only to new members and even those who have never posted before.? Those posting will go to the moderator(s) for approval, hence, they don't appear until reviewed and approved.
This is to discourage bogus or inappropriate messages and that is why this site is basically clear of any spam or other bad stuff.
After two consecutive approved postings by the new or same member, that delay no longer applies and future postings are not delayed.
I hope this explains the delay of some postings.
