I think our office meets your criteria for best testers. In support of the changes you are developing, we would like to help. I do have some questions, so feel free to contact me.
I will follow up with you when the Client Server beta is rolled out. We anticipate that will be late October, early November.
Yes! We are currently on version 16.2.8 on the cloud. We have been on softdent since version 6 I believe and are currently in the process of converting to chartless so I am very excited to see the new updates that are in the works for the charting module! Now if we can get a few more 3rd party integrations going, we would be in some business!!
