srayne, no help file for the moment I'm afraid. By the time of the next release, I will try to write one. In the meantime reading my replies in this thread should address the common how-tos.
Regarding your smartphone, it sounds like you need to install the .net compact framework 3.5 from Microsoft which is a requirement of SkyAngel.
You're quite correct that our TAF parser doesn't yet understand QNH forecasts; I'll get this fixed.
VictorGolf you can't actually add airfields in this version so you haven't missed anything! You can, however, ctrl-click on the map to create a user-defined waypoint that you can treat as an airfield. Unfortunately this won't be saved next time you open the software. This is an issue that'll be addressed for the next release.
Thanks all!
