My tags have disappeared from my Tipasa Homepage
The tags that you add to ILL requests in Tipasa are only shown on the Homepage when they are attached to an active request. When the request is closed, the number behind your tag might go down, sometimes even to zero. This doesn't mean your tags have disappeared or have been deleted, just that you don't have any active request with that specific tag.
You can find more information on tags on the Manage Tags page.
