I need to add functionalities to my Moodle platform.
The thing is that I can't find a plugin that does exactly the things I want. I'm thinking of two options:
1. Develop new Moodle plugins that do exactly what I want.
2. Change the ones that exist (choosing look alike ones).
I already tried option 2, because I feel that it is more easy to follow. The thing is that when I change the plugins and try to upload them to Moodle, the new zip file is never accepted.
Can you help me? What should I do and what am I probably doing wrong on option 2?
Thanks a lot
