You can find teamspaces that are interesting to you in one of two ways:
When you create a teamspace it is automatically added to your list of teamspaces. When you enter a teamspace that is not on your list, you will be asked if you want to add the teamspace to your own list of teamspaces. Adding a teamspace makes it easier to locate and enter it the next time you use the application.
You can also add a teamspace to your own list using the add to my teamspaces action button. Once the teamspace is added, it will appear in the list of available teamspaces whenever you sign in to the TCM application.
