I am using the Virtue Premium theme and I would like to know if it is possible to have a single page that acts like a bulletin board where I can provide some headings and then people visiting the site can add/edit that particular page themselves without having access to edit anything else on the site – just that page.
My objective is to list art galleries and shops, and then let people add themselves under the ones that show their work. It would be ideal if I could assign them an id of sorts that would let them do this rather than giving access to the public at large.

Thanks
Susan
