On this page: https://www.adventuregamestudio.co.uk/site/ags/ -- the "Ags Resources" link is broken -- url is: http://www.americangirlscouts.org/agsresources/
Also in the Critics Lounge there is a sticky entitled: Quick Links to Forum Tutorials! and is found here: https://www.adventuregamestudio.co.uk/forums/index.php?topic=30939.0
The actual forum threads listed, a majority of them have images that don't seem to load anymore, and thus rendering some of those threads unusable.
A majority of those tutorials and links are broken, needs to be cleaned up.
