I don't really know what I can share, other than that I've suddenly been placed on moderated status (a screen pops up saying my post is awaiting review). Some of my posts are getting through, and others aren't. I don't think I've done anything wrong. Perhaps they will eventually explain it to me. I'd say it's about 50-50 that this post gets through.

Don't sweat it, you are doing alright.
Ring a bell?

Contributing to the conversation is one thing, but spamming the same thing over and over is another.
