Tags are a special class of Profile that can be thought of as "post-it" notes which you can attach to your Entries. They are particularly handy for managing your workflow and quick task assignments. Some useful tags might be "Needs more photos" or "Needs dimensions." 

Tags exist in the upper right corner of your Entries, so they are "outside" of the rest of the data pertaining to the Entry. Tags are easily searchable by the specific tag name..

To create a Tag while editing or creating an Entry, follow these steps:

• Click on the "tags..." icon in the upper right corner
• Click the + button in the Edit Tags popup screen
• Give your Tag a name and an optional description
• Click “Create”.
• Once you've created your Tags they will be available to use when you are creating or editing your Entries.
