All the links under the "RPG's RGSS tutorials" section are broken.
Also, for those of us, who obsessively question why something is the way it is and aren't happpy until we understand stuff, I found this "RGSS Reference Manual" at
http://k-du.de/rgss/. I found this a bit more enlightening that some of the "RGSS basics" or "Intro to RGSS Scripting" tutorials that are on the web. It breaks down the syntax and library entries, and actually explains what they mean and why they are used.
Perhaps this can be added to the sticky information.
