The link on your website for the official C2 manual isn't working:
It says "Download the Official Construct 2 Manual (2.2mb)" but it just links back to the website. I'm going to be going on a 7 month western Pacific deployment soon and won't have internet during most of that timeframe, so I won't have a way to reference the online manual. Is this offline manual hosted anywhere else?
Your Construct 2 application has a copy of that manual. So, you probably don't need that.
