Does anyone know a better way of making concept maps than using one of the standard maps and inserting relationship lines etc.? Wikipedia has a description of concept maps and I have used something similar when trying to understand a really complex subject of interelated factors. ( I was looking at neurotransmitters, anti-epileptic drugs and anti -psychotics--Mega complicated! but the map was great at sorting out all the relationships) The problem was that repeated heirarchies were not always appropriate. Something that allowed more than one main topic would help. Thanks

You could try creating several floating topics (which can have subtopics) and connecting these with relationship lines. This will give you more than one central topic in the map.
