I like that you can create multiple accounts so if one account gets hacked or deleted then other users won't be affected! There are certain features such as creating daily logs/tasks where there's no way around having someone else enter in your data because once again this will get lost with another user logging into their own separate area etc - just make sure everyone uses unique logins otherwise all those important records could end up somewhere completely different from eachother!! Great program but keep backups everywhere (hard drive space at least).
It really helps when things go wrong especially after hours working late sometimes forgetting about something until next day comes along :).
