Sorry, this is not a 'normal' blog post!
One of the reasons I started with this blog (September 2010) was my frustration that the articles I published with the Adobe Community Publishing did not reach users easily. Those articles try to explain in depth the basic rules of variables and advanced actions in Adobe Captivate 5 (and sometimes also for version 4) and mostly I offer a practice file. In this blog you will find some links to those articles.
Perhaps this list with links to all the published articles, and a small explanation could be useful. The list is posted on workspaces.acrobat.com, I published it and you can download it anonymously. As usual, I appreciate any comment or suggestion:
