Hello javiersantos, Thanks for your reply. I also posted my question on the wordpress.org forums and got an even simpler solution. Here it is:
If you want to have another instance of WP in your WAMP server, just create a new, empty database for it, create a new folder for it in WAMP's 'www' folder, unpack the WP files to this folder and run the install No need for 'multisite'.
e.g.: First site is here:
C:\WAMP\www\wordpress and you access it with http://localhost/wordpress
Second site would be here:
C:\WAMP\www\wordpress2 and you access it with http://localhost/wordpress2
... and so on and so on. Your only limitation is the space on your hard drive.
Here's my reply:
Yay! It worked. I created a new directory wamp/www/wp2/, then I copied all the WordPress files there, then I went thru the php/sql db setup steps, then the WP setup steps, then I hit install and there it is! Another separate site connected to a separate php/sql db. Very nice. Just what I wanted. Now I can play around with other themes and work on a variety of test sites in parallel. Now I can really start learning more about WP.
When I was doing all the research about this I didn't come across anything that indicated it was this easy. Huh! Oh, well. Or maybe I did see something but overlooked it.
Thanks again, greatly appreciated.
javiersantos: When I read your solution I have to admit I have no idea how to set up different ports for Apache and MySQL. That level of complexity would likely be a show-stopper for me. But thanks again for your reply.
