When you first use the system, press the "Help" button in the top frame, then select the "general help for newcomers" link at the top of the screen. Each screen configuration has its own special help file, so if you get into a situation you haven't seen before, "Help" should explain what is being shown.
If you have any problems about the functioning of the program (not the actual botanical data, which I have nothing to do with!), please send them to me at firstname.lastname@example.org.
