I like how easy it was to set up through their website, as well as using social media sites for marketing purposes. The customer service is always great with any questions that arise during setup or use of our system! There are several virtual offices in my area so we can choose which one works best for us at this time but all have been very helpful from start to finish when setting them up. We haven't used many features yet since they only just launched last month (July) but everything seems fairly intuitive once you figure out where things go/what buttons do what etc. It's not something that needs much explaining either because there isn't too much involved other than getting your email address correct before signing into the site itself. If anyone has specific issues please let me know - I'm happy to help answer those if needed. As mentioned above though, nothing really stands out negatively except maybe.
