@samsgrammy, the best way to get quick answers to questions about DPW features and issues is to contact us through our support system, which you can do by either clicking the “Support” tab on the left side our our website or by emailing us at firstname.lastname@example.org.
The “Note Card”, “Calendar”, etc. links you are seeing on member’s DPW Gallery websites are not categories, which are used for organizing the galleries’ artwork, but instead are custom store item pages the artists have created. You can also create custom event and print (reproductions) pages.
You can read about how to do this here:
