Thanks Colin ... Using the solution you mention, I will change the text of the messages that come with the core of moodle but I would still obtain generic messages in which only the reference to the resource or activity involved in the condition changes. I do not want to show generic messages like:
"You achieve a required score in Furum 1"
or
"You achieve a required score in Assignment 2"
or
"You achieve a required score in Live Videoconference"
I want to customize those messages where I can refer to my own scales. Something like:
"You get 15 points in Forum 1"
or
"You get 12 points in Assignment 2"
or
"You attend the Live Videoconference"
