Finding an old post/comment
As well as the usual slow and labourious ways to find an old post/comment, Scooploop provides a file you may not be aware of, that contains all of them, which you can then search using your browser's Find facility. This is a plain text file, which means that the links aren't clickable, but it will let you know what you said, and perhaps to whom. Then, depending on the circumstances, you can go to the appropriate group etc. The file is called 'My Scooploop Information' in Settings: https://www.scooploop.com/people/settings/my-scooploop-information/
