If I create custom taxonomies for tags and categories in custompress, they show up in both the admin screen in the post or page/attachment menu on the left column in the post/page/attachment itself. I do not want to confuse the users regarding which categories and tags are to be used, the CustomPress vs. the standard wp tags and categories.
If using Custompress taxonomies, can the standard wordpress categories and tags be suppressed (not displayed)?
