I'm new in moodle community, and i am working on a project using moodle. Ι have successfully installed moodle with XAMPP and i'm trying to configure it in my way. I was wondering whether is possible to create a php extend application which will send alerts in users' mobile phones (wml) when e.g. some users have been registerd to a class or some users request α detail grade form. Is that possible? I am grateful for your time, thank you in advance!
