Your recent moderated post was approved within an hour. Unfortunately we have to take extreme measures to combat violently aggresive spammers and hackers. Once you have proven yourself as a reliable poster (after x amount of posts etc.), all of your posts will show instantly.
I find this very annoying because it seems like it takes a very long time!
I don't think anyone approves anything. The system just does that to the new posters.
You will want to copy your posts before hitting post in case it doesn't post then just re-past it and try again.
After X number of posts it will quit doing it and you'll be able to post. I see you already know how many X is.
Like I said just copy your post before hitting post in case you lose it and re-post it until it quits doing it.
Welcome to the forum, hopefully you'll have more to contribute than some of the senior members do on here, if you know what I mean.
