Ok so I was having trouble searching the forums quickly for common issues/solutions so I created a public Google custom search.
Search GSAP forum and GSAP related codepens here
// Added tabs to filter codepen only and forum only results
Tip: To remove results from flash / actionscript forums, append the following to your search: -actionscript
Right now it only searches URLs including the following:
http://greensock.com/forums/topic
http://codepen.io/GreenSock/
http://codepen.io/osublake/
http://codepen.io/rhernando/
// Added from osublake post #2
http://codepen.io/MAW/
http://codepen.io/jonathan/
http://codepen.io/bassta/
http://codepen.io/chrisgannon/
http://codepen.io/jamiejefferson/
http://codepen.io/grayghostvisuals/
Keep in mind if Google hasn't yet indexed a new posting, that it will not show up in the results.
Also, it seems like some moderators use the GreenSock codepen account, so if there are other codepen accounts that predominantly have GSAP animations, let me know here? And I will happily add them.
