Update:
I am about done with this phase and I'm feeling good about the results of what has been accomplished so far.
There is still a long long way to go to modernize this site and to get rid of most of the table tags, make the site more responsive across devices and clean up the legacy code in general.
I was going to change the login to use jQuery and AJAX, but because there are so many PHP permissions for every step of the process that is dependent on if a user is logged in or not, and this requires all the PHP pages to refresh, I'm removing this small task off the current TODO list.
Now, I need to think what pages, tables and other things I will tackle in the next phase.
So far so good.
Thanks for all the feedback. I really appreciate it and I could not do this "site upgrading" job without all of your feedback and help, watching the site every step and giving me feedback when things look odd and I have not corrected it within a few seconds or even minutes.
I'm pretty confident in my CSS and Javascript / jQuery skills these days, and I guess I should apologize for being busy on my "cyberspace situational awareness" game-engine project for two years and not modernizing the site years before. I wish there were two or three of me, but one is more than enough to drive people crazy, LOL.
I am sorry if I have let you down in not modernizing this site earlier. Actually, it's much easier to work on this site (CSS, JS, jQuery, and HTML) versus programming a parallel, multithreaded cybersecurity visualization app using C# and the Unity 3D game engine; so updating the site is not technically difficult, but it does require a lot of time on screen and keyboard.
Thanks again for all your patience with me.
I'M BACK
