I have space editor rights, but was wondering... how do I actually edit the "overview" of the page? I do not know where to find the options to edit the page itself. I have taken over the role after the previous person has set up the space.
Let me branch this off into a new discussion since we might be mixing apples with oranges.
Welcome to SCN.
By 'overview' do you mean the overview page, like this? What you should do is reach out to the content strategist listed for the space. They're all listed in the and are SAP employees (so you can find them in the company eMail directory). They'll make sure you're setup with your permissions and provide information on editing space overview pages. You can also reach out to me offline.
