In TextOut, you have the ability to join and text in more than one Workspace. In order to text in different Workspaces, you only need one account in TextOut.
You can toggle between your different Workspaces by clicking on the blue downward arrow at the top left-hand corner of your TextOut screen and directly next to your Workspace name. This will pull down a menu of Workspaces you are a member of and you can select the one you want to enter from here.
If you do accidentally create two TextOut accounts, we cannot merge them. Select one to use as your primary account and edit this in your Account Profile.
