When adding a message in a particular task, everyone assigned see's the message unless you create a rule to only have some people see it. Then you can add others to certain messages. This is how it stands now. I would love to be able to have a chat box, like the one we use to get to help desk or some way I can speak with my internal users and not have it include the guest accounts and not have to remember to include some people some of the time. We really want to utilize the system and keep organized by having everything in one spot. Our guest users are our customers, sometimes a task may be delayed for a reason that we do not want to share with, but we use the message feature to communicate a lot with them. I hope this makes sense! Thank you in advance for your consideration!
