complete website layout

The website layout should be completed, here are the database tables, functional specifications and the design pictures

1) Wouldn't it be better to replace artefact 'Project' with standard type 'Organisation?' That would mean the maintenance function is already in place
2) New contribution:
At the moment: Article, Story, Event, Organisation, Person. Please adjust to: Article, Story, Event, Project, Volunteer, Task.
3) Next to "Visible for:" button in the red bar please add button "May be edited by:"
4) From the contact page, the buttons "events that start" and "events which are running" may be removed as far as I'm concerned
