My DC’s school is encouraging us to use Classlist so no Whatsapp has been setup by the parents rep.
Personally I think it is a pain, asks for credentiels every other time I log in from my phone, takes time to launch... It feels way too official for the kind of small talk that would happen on whatsapp - plus I am not sure the school can’t read everything so wouldn’t discuss how much to give for teacher’s presents for example.
I see the point for official school communication, and for school events etc.
But what are the advantages compared to Whatsapp for parents to talk to eachother?
