I will be 77 years old in a few weeks and the last 5 years I had built a network of friends and family of course, like everyone else, posted family pictures for posterity… anyway, was locked out due to a technicality and was so very lonely after 3 months I started a new account – my frieds were excited to reconnect and I felt like a kid in a candy store. 5 Days later am locked out again and bereft.
A simple chat (slack style) it's enough. Just having the possibility to send messages either single user or team (#channel). But please don't forgive to give an useful appeal to mobile app (worst error of competitors is, have a good app but totally no mobile friendly!) i would expect to have a similar whatsapp or slack app for messaging within the slack mobile app!
