Thanks much!
My search of the site got me 2544 hits and ironically I still don't see this one among them!
This is a very complicated forum type to understand (posts are from last to first, and then there is the issue of search results being defined as 'In Title' or 'In Contents' - I've only been with Joomla for a couple days and most of that was reading documentation...I'll get used to it, and my search skills here will improve as I get a better grasp of exactly what I need to search for (I searched link - url this time.)
Also, I don't know that I would have followed the instructions in that post had you not directed me to it because I am running 1.5 (no mention of rc3 on it) and I had found a post elsewhere that said DO NOT add internal links using the external links option
!
I've gone with the suggestion in that post and it worked beautifully!
I thank you SO much for taking the time to help me out here!
