Alright, I'm using Notepad++ per your recommendation and so far so good. I am doing my first attempt on a site that is not so critical if I make a mistake. I've gone thru the steps at https://premium.wpmudev.org/wpmu-and-buddypress-installation/creating-a-network-by-enabling-wordpress-multisite/
and now I at the part near the bottom that has the header "Checking out your Network Admin dashboard area". I did log out and back in just to be sure, and I do not see "Network Admin link in the top right of the WordPress Admin". The instructions the network enabling page says "Once you have completed all these steps and uploaded all files". So I am guessing there is more I need to upload, I just do not know what they are. I have not installed BP yet, and I am trying to see if there is any other files I need to upload.
Please advise. (I have a special banana dessert ready for you once this gets all figured out).
