Ok, this is the test post…
and a post in the middle…
Now lets see if I can re-open the thread and link to just one post. And hey, I’m upping my post count!
Now, hopefully, a link to the first post in this thread.
And the second…
I did it! Yay me!
Such shameless post padding, dave!

. . . or Manny would’ve locked this and said asked and answered. 
Although it may be post count masturbation, I’ve been looking for a way to do this, too. [sub]Link back to another post, that is. ;)[/sub]
Thanks.
Interesting sig, but why don’t you quote your namesake Plato?
How exactly do you do that, anyways?
Every poster’s profile page has a link to their last post. It looks like this:
http://boards.straightdope.com/sdmb/showthread.php?postid=NNNNNNN#postNNNNNNN
Replace the NNNNNNN (in both places) with the postid of the post you want to link to. You can find the post id by moving your mouse over the quote button for the desired post and looking at your browser’s status bar.
Here is another tip. If you want to see how someone coded something in their post, click on the quote button. Their post with the coding will be in the reply box.
I think Plato would have also greatly appreciated the work this quote is from. As he put it, “They deem him their worst enemy who tells them the truth.”
That’s funny, I interpreted the username as Play-Doh 
I had sat there and wondered if maybe you had some strange fascination with Play-doh or something.
Both. It’s multi-dimensional.
