I would like to see sms messeging integrated in Chamilo. It could be an option in the Personal Messenger to choose sms as "Type".
In the Admin section it should be possible to choose who is allowed to send sms messages and also to
choose SMS provider. I suggest a small list of well known international providers like twilio and clickatell to choose from.
Even better if it is also possible to insert your own preferred provider manually.
This feature is needed for informing teachers, students and parents of sudden change of plans.
