The best thing about alosign is that it works with all computers, not just Macs or Windows machines like other similar apps out there! I dislike nothing so far (and yes this app has been around for awhile).
It's great because we can send our entire team an internal email without having them be connected through their phones/email systems - which gets very frustrating at times when they're miles away during normal business hours but have access via phone-in / video chat afterhours etc.. The ability for me as an individual user, or team member of individuals who may not have full knowledge about using computers can easily access their accounts from anywhere that has internet connection with out having them be physically at my desk! I am able use this feature while walking around campus during lunch time etc without being near any PC's which is great when it comes down to productivity!!
