Working for NASA, I have produced a bespoke Access Database for environmental issues on various sites here in Houston. It has been developed over the past year and is quite comprehensive. As a result we needed a help file to support our users. This was an add on and not required so therefore could not be officially funded by NASA. I don't mind funding it's purchase myself but obviously I don't want a heavy weight package costing a fortune. On the other hand I also don't want a Mickey Mouse freebie package either. I found the Dr Explain system available which seemed perfect for our needs. Professional and feature rich without costing a fortune. I have started to put together our help file now and have found nothing at all to criticize.
