Due to changes in the BBS, some EXTREMELY USEFUL posts about Actionscript 2.0 programming from back in the day are much harder to find. For my own use, and to make them a bit more available for more users working on the Flash Forward 2022 jam, I'm copying the content and links from the original AS Main: into this post and will currate the content from time to time. Please report any broken links if they sneak in.
