How often do you use Discord?
Daily.
If you could improve PRO's Discord with one suggestion, what would it be?
Allow voice chat. There are several channels, and they are all locked. If there is a way to gain access to them, it's not mentioned anywhere in the rules or anywhere else I've been able to find; perhaps an updated F.A.Q. is in order, or at the very least, information on how to access restricted features of the Discord server should be added into the Rules section.
