The interface of this program makes it easy to use by anyone who wants to join or has already joined any group within unaity. I love that there are so many different groups which can be used as you see fit in your day-to-day life. There's also no limit to how long one may spend using the service once they have signed up. This could potentially make people feel like their time would run out quickly if not utilised correctly but luckily i found that my experience was quite opposite from what others had said about them feeling rushed when signing up. They do offer unlimited hours free of charge however those hours need to then all be used before another month begins meaning some users find themselves unable to take advantage of the benefits offered due to limited times being available each week/month. Overall great tool! It allows me to talk to friends across various fields without having to pay expensive call rates.
