For my clarification please:

I'm assuming we are not using WED here.

1. A single entity can have 100 skills.
2. A skill can be attached using dot notation as in object oriented programmming
3. They are effectively variables that are used exclusively with entities
4. They can be aliased for clarity

local/global or both kind of "variables" ????

Could someone list the properties of flags please. I know they are boolean but I still get confused by them.

Thanks
