It is very easy for me as I am used to using email, but it has so many features that are not always necessary or useful at all times! There's also nothing wrong about this program really - if you're looking into getting another one then there isn't much different between them in my opinion (although gwapp may be more expensive). You can use most of its functions without paying any money; however some things do require payment like scheduling meetings etc., which could get annoying sometimes when they have such great discounts available otherwise. Easy-to-use interface makes communicating easier by letting people know what time we will meet up next easily.
