Hi Mary!
I currently have my changes hosted on GitHub (https://github.com/DanaOHara/Moodle27Teses.git). I can't find a hosting server with access to old PHP versions, so I'll set up a local server at home if needed. Most modifications are on the Login folder, specifically on index.php, and the "password" view I made at index_formsecondpart.html.
The most relevant part of my code should be line151 on index.php, on line 151 I make a redirection, if the password us empty i redirect to the second view (index_formsecondpart), otherwise I login normally.
thank U
