I love that you can send messages straight from your account so if someone is being naughty they don't have time in class/club etc while also not having access via email which makes it easy! There's no video calling feature like some of my friends seem prefer but this works well enough at least when we're within school hours (which isn' t often). Sometimes there are delays during peak times between messaging people as sometimes students will be away doing something else instead - however once those kids return things go back online quickly without delay again :) Would recommend everyone use especially considering how cheap its per message compared others out now including WhatsApp!! This has been great allowing me quick contact options even outside regular working days & evenings too where i'm home alone most nights after work due do night shifts :D Love using all features available such n.
