Sorry about that, it appears some of your messages had been caught in our spam filter and had been missed when we double check through it. I've now marked them all as not spam so hopefully it will learn not to pull them through in future.
I just replied to a post and can see that my reply is pending and whilst I noticed that I also noted that I have a few posts under the "rejected items" tab. I am attaching a screenshot for you here. Why were they rejected?
