Something a correspondent said in a post pointed me here and I tripped over this great extension.
Problem now resolved! This plugin is the answer to my prayers!
This extension has added greatly to my new website. Thank you Kunena!
I found that the documentation was exteremly thorough, but it took me several hours of reading through a 60+ page pdf before I was confident that I had cracked the procedure.
This product does exactly what it says on the tin. This is a must have component for serious Joomla users. It really is first class.
