Steps 14 and 15 in my explanation in reply number 15 are an attempt to describe how to delete the extra post. The "Remove" button is in the same area as "Reply" and "Quote"
Really, you don't have to do the copy/paste parts if you initially start the topic knowing that you will have a link in it that will need approval. I wrote the "guide" with the assumption that you have already generated the post without considering the "Awaiting approval" whammy, and now have to go back and rebuild a new one without the wammy. If you are posting expecting to be hit by the "wammy" and want to avoid it, you could always start with step 5, go through to step 11, then just type what you want your post to say, with it's links.
I would include this "guide" in my older
forum code advice thread, but the "awaiting approval" function serves a purpose, and I only wish to support subversion of that function so far...
