I love that it is easy to use for my small business because there are many features available! It can be confusing at first but once you get used its great!! We have been able solve our communication needs by using this tool so far we haven't had any issues or problems solving them if they did arise though i am sure their would help support right away through chat/email etc :) Would recommend anyone who wants ease of management within an office environment as well has security concerns about sensitive information like credit card numbers ect should definitely consider stack field. Real time secure email messaging between employees working remotely from home without having access outside emails which could potentially compromise all confidential info sent via e mail services such us outlook webmail service (HotMail).
