Find the right level of permissions...
In BrewPlanner PRO you can have as many additional users as you'd like, and now you can give them just the level of access they need.
In version 2.48.17* or later, if a "Customizable" new user is created, you can control exactly what they can see and what they can edit.
* To find the version you're on, select "Help & contact" from the upper left-hand menu, scroll all the way to the very bottom and it is in the lower right-hand corner.
