I tried to post a reply to the thread
http://chdk.setepontos.com/index.php/topic,1489.0.html and got this error message for both preview and post:
Not Acceptable
An appropriate representation of the requested resource /index.php could not be found on this server.
Apache/1.3.39 Server at chdk.setepontos.com Port 80
Also trying to post the same message in a new thread failed the same way. I then rewrote some of the message, possibly removing some offending whitespace characters that may have been there due to a cut&paste operation and succeeded.
The original content was similar but to but not exactly like my reply in
