Andy, in your first post you ask for suggestions of possible ideas to write about...in 'Plants for a Future' it says of nettles:
The leaves are extremely rich in vitamins and minerals
Avoid older leaves as they develop gritty particles (cystoliths) which act as an irritant to the kidneys
Use the leaves to make tea
The stems contain a strong flax-like fibre that can be used for making string, cloth and paper
The plant is an essential ingredient of 'Quick Return' (??) herbal compost activator and are an excellent addition to the compost heap
They can be used to make an organic liquid feed for plants that also acts as an insect repellent
the growing plant increases the essential oil content of nearby plants, thus making them more resitant to insect pests
...and John Yeoman has a recipe for a savory nettle cake in 'Self Reliance'
You could possibly add that nettles aren't a very good salad vegetable
