Show "Created by" read-only field in Document Edit view. Update size of TinyMCE widget in Document Edit/Create views. Change user property name to founder in Document model and update files according to this change (now founder is used in Group and Document models). Remove not used variables and imports in views/site/docs/edit.py. Refactor EditForm and CreateForm in views/site/docs/edit.py so that EditForm inherits from CreateForm and just extends it.
