When you post to RMAM through your news reader/browser, your news
server automatically e-mails the post to the RMAM moderation
facilities. There may be a delay depending on how busy the moderators
are. When it is approved it gets posted through the moderation news
server, which is On-ramp. So you may then experience a delay due to
the propogation from On-ramp to your own news service. Your post may
also get to many other news servers more quickly than if you posted to
an unmoderated newsgroup on your own news server. This is a particular
distinction of moderated newsgroups. If you are impatient, you can
check www.zippo.com, which is a free web-based news service that seems
to have very little lag for RMAM.
