Thanks Dave,
I attempted to use your code and I have not given up but cannot get it to work at this point yet. I did go back and use the following that I have been able to get to work.
RewriteEngine on
#RewriteBase /modx
RewriteRule ^/modx/manager/.* - [L]
RewriteRule ^/modx/assets/.* - [L]
RewriteRule ^/modx/(.*).html /modx/index.php?q=$1 [L,QSA]
For other newbees like me, this installation resided in the /modx directory.
I still am going to go back and test bits of your code as I am getting better at understanding the language there.
One key thing that I found is that I need to uncheck "cachable" on the pages that deliver dynamic links. Otherwise pages will not be delivered.
Thank you again!! Thomas
