It appears perhaps the webmasterworld automatic link redirection scheme prevents linking to specific posts.
I tried posting a link to a specific message and the redirect only goes to the top of the thread, although it looks like the redirect is passed the message number.
I did search around but only found older posts on this topic.
Perhaps there is a work around. It would be very useful to again link to specific posts.
Wow and the three letters "ExExEx" becomes #*$!
