Editing content
Up one level
There is a common way of editing all content in the site, no matter what type of content it is.
When you are inside a content item that you can edit, you get a green border around the content.
Along the top of the content you will see several tabs: View, Edit, Properties and Sharing.
The most interesting one of these to you is the Edit tab, which is where you can change the information contained in any content item — Projects, Project Reports, etc.
If you don't see the green border, you do not have editing permissions. In general, you can't edit things that you don't own or aren't given permission to edit explicitly via groups or sharing privileges.
