Cool. Happy that you were able to do that.
Tho, for a lot of students n some office workers, whatsapp grps are the main means of communication. Every college/class has an official classroom/batch whatsapp group and porting all those folk into a stable opensource/foss alternative is a task that needs a lot of time n man power.
