I'm on a computer science course, and a few of my peers made a whatsapp group for anybody on the course to join.
There are about 100 or so people in the group, and often I "lurk" on it to get help on various topics since there is sometimes some actual useful information disclosed. However, the group admins and some of their friends use the group as though they're the only ones there, meaning there's so much spam of simple idle "banter" that it actually drains my mobile data.
I also use whatsapp to message other groups or friends, so I don't want deny whatsapp as a whole of using my mobile data.
Is there a way to make a group only "receive" messages when connected via wifi?
Thanks in advance.
