[SOLVED]tag or additional categories from frontend

Hi, I purchased edocman yesterday and I just started using it. I have to manage the documents of a company, documents must be traceable also by department. To manage the department, I tried two ways: tag and subcategories of the main category forms, but both methods are missing something.
1) Tag and additional categories cannot be inserted from frontend. Is it true? Is there a solution?
2) Tags are visible only in the document detail? Is it possible to display them in a table layout?
3) Can you suggest me an organization that allows us to manage from frontend documents organized by department and by main category?
I hope I was clear.
thank you

I found that I can place the tag from frontend but not the additional category. The problem remains because using the table theme I do not see the tag and I cannot even make a tag search, so the only possibility is to add additional category but I cannot insert it by frontend. Help me please.
