Content creation

Hi. I am developing a site that will be using the Memory Game and desperately need to display a leaderboard that can be reset once a week. Is this possible? URGENT NEED. Thanks for your time

I would like to add dialog card content to an existing presentation I have saved. I have been searching and cannot figure it out. Can anyone help?

I have uploaded some images to my H5P but they have names such as image-4rhgnj.png. How can I rename the image? I renamed them in dropbox and reloaded tham but it didn't work. I renamed them in my Wordpress media library but that didn't work. Thanks for any help.
