Dan,
Thanks for the post. The original post has been fixed & should now be visible again.
To reduce spam, PoA places any post that contains links from a "new" poster into a moderation queue. If the post is approved and subsequently edited by the original poster, it ends up in moderation again. Since you were a "new" poster (under 5-10 posts), the message ended up in moderation when you edited it to include the link. Once you make a few more posts here at PoA, the restriction will be lifted and you'll be able to post without moderation.
I've approved the post and all should be well.
Welcome to PoA.
Bill
