That's the theory, but unfortunately the auto-mod has developed a mind of its own, and periodically starts moderating perfectly good posts for no apparent reason. :o Even more unfortunately, it seems to develop grudges against certain members, so once it starts moderating your posts, it carries on, no matter how innocent they may be.
The forum is shortly moving to Discourse, so there's no point in trying to fix this increasingly-broken system now. We can only apologise for the inconvenience, and ask you to bear with us until we move to our shiny new system.
The moderators do try to approve posts as quickly as possible, but at weekends in particular, we're sometimes a bit thin on the ground.
