Due to overwhelming demand, I have started work on a "proper" manual for ADRIFT 5. There will be two versions - a context sensitive (i.e. it will be possible to go straight to the relevant section of the help directly from the application) offline version, and an online version.
You can see the online version in it's current state at http://help.adrift.co. Please remember that it is still under construction. However, I would welcome any feedback.
