As you would expect, TPM's servers and message board software are among the best in the industry but, as with all high-quality technology, you need to learn to walk before you can run.  Here's how to submit a post without seeing it appear multiple times in the list:

1). Near the top of the page, click the "Blog Now" link.  Wait five or ten minutes minutes for your posting request to be "approved" by the server.

2). Compose your post.  Be sure to highlight your entire post and copy it to the clipboard before you hit Submit.  If the server is busy, your post could be put into a state known as "vapor queue" which is similar to being lost, but far more advanced and technical.  Anyway, if you've worked hard on your post, you'll want a copy so you can retrieve it later.

3). Click Submit.  Your browser will appear to hang, but actually your post is being carefully submitted, letter by letter--each letter carefully checked for correctness before it's allowed onto the server.  This is a slower technique than some message boards employ, but it results in a much higher quality end product.  Believe me, when you finally see your post on the page, you'll agree that it was well worth the wait. 

4). Wait five minutes or so.  Eventually you'll get a "500 Server Error".  That's TPM's way of letting you know that your submission has been accepted.

Now go back and look for your post.  You won't see it, but never fear (and don't post it again unless you want to see it again).  In five or ten minutes, your post will show up in the list.  If you click the link, you'll get a page telling you that your post doesn't exist.  That's TPM's way of letting you know that your post exists, and that it has been put into the server's "holding pattern" stage.  The holding pattern is industry standard technology, used to guarantee that conversation doesn't occur too quickly, which can cause user confusion and disagreement.  Also, it keeps posts from "colliding" with each other, which can cause "packet hangs" and excessive "metasyntactic variability".  Think of it this way: your post is there, circling over the message board, waiting for clearance to land.  Once the server's control tower finds a free space to park your post, you'll be on the ground in no time.  Click the link multiple times.  Refresh the page.  Click the TPMCafe' link and try again.  Suddenly, like magic, your post appears.  Viola!

Trust me: once you've become accustomed to using the TPM system and its high quality posting software, you'll never be satisfied posting on a "quickie" message board again.  Previewing posts is for newbies.  OK, I'm hitting Submit--see you in 30 minutes or so!
