You’ve only created two topics in the #videos category, Mike:
Stavanger central park fountain
I found these by looking at your profile and clicking “topics”: https://greyarro.ws/u/speedbird/activity/topics then just scanning that list for the Videos category.
Or a slight modification on the reply by @milkmanchris earlier also works and shows the same two if you try this: https://greyarro.ws/search?q=%40Speedbird%20youtube%20%23videos
