I added the left menu links from the other OR template's main.html to this file to make it complete.
Modify the .css file to your needs.
That's it. Add the Xoops' "Home" link somewhere on the main page to get back to the XOOPS site and a OR link on XOOPS index page to get to OR script.
MXDirectory clones:
Changing table names, file names, and codes like this:
change all "XDIR" to "MXXI or whatever"
change all "xdir" to "mxxi or whatever"
so this directory is different from the other directories.
Hope that helps since it worked out great for me.
