Tags are keywords that you can give to artefacts and pages in your portfolio to find them more easily later on.
A site administrator must have the tag cloud enabled for you to use this feature.
You can see your tag cloud in the sidebar when you are in the Content and Portfolio areas. Configure how many different tags you wish to display in your tag cloud in your account settings.
The more you use a tag for your files, journal entries and pages, the bigger its font size in the tag cloud.
On the My tags page you see all your tags and the artefacts and pages associated with them. You have a number of filter options to show only the resources that you wish to see.
You can edit your tags to correct spelling mistakes or delete a tag.
