Can I add categories, tags, and notes to my Site Lists in Workspace?

Yes, you can. To add categories, tags, and notes to a site list just go to the Site Lists section of Workspace and click the  icon.

Just like with Keywords, you can put in multiple categories and tags by placing a comma (,) between each item. For example:

Tags: tag1,tag2,tag3

Categories: category1,category2,category3
