Display original site name, etc.

1) Display original site name I'd like to display in each post a black box with the original site name, such as 'EIKE' in this sample: https://alternative-presseschau.com/category/eike/ Which is the appropriate setting, please? 2) Display original author's name I'd like to display in each post the original author's name (instead of local admin's name). Which is the appropriate setting, please? 2a) Alternatively, do not display any author's name. Again, which is the appropriate setting?   Best regards, Peter
