i'm building the taxonomy/pages users will see and one question arises - can the drupal forms for page, story, forum, comments, etc. a) allow users to add/suggest a new category and b) include open text fields for users to enter a list of terms not yet listed (i.e. an investigator finds a new lead/suspect and wants to name specifics as part of the page/story classification/meta x,y,z) - i just need to build an open text field into the form - how do i do this?
