I don't think we need a Whatsapp group. But, like @mefistoreyon
already said, it's killing the forum. Besides, we already got an IRC channel on freenode if we need to discuss things directly; the logs are online as well so everyone who wants to can read all of it to stay tuned what's going on. Creating a Whatsapp group will only get a few people involved and others won't be able to join, so we would be creating groups inside groups which isn't the right way to do things together. Just my opinion.
