I would like to edit one of my tutorial but when I hit the Edit this tutorial link, it brings me back to the top page of tutorials (https://www.scirra.com/tutorials/top).
Thank you for your attention.
This is likely due to a large spam attack prior to the xmas holiday period.
Tom was forced to disable editing/adding new tutorials until he can update the automatic spam filters, which due to the holidays, won't be until next week.
Hopefully, they will then be back up soon after.
