Did my first batch of nettle manure. Today, I used it. The family hastily
vacated the garden and are still barely speaking to me beyond "You are NEVER
using that stuff again - EVER!" Although the wesbite warned that it was
likely to be a bit whiffy, I was unprepared. Furthermore, I'm sure said
site claims that the smell goes away pretty quickly. An hour later and it
still pongs.

And there's a snail lying on his back in the area I fed. He keeps trying to
turn over and then appears to change his mind. Obviously, it's too much for
him too!

Nettles make lovely wines and beers, so maybe that snail was a bit
tipsy? :-) From your description, I would say that you have made too
strong an infusion, i.e. either too many nettles or too little water. I
always dilute mine with 50/50 rain-water before applying it to plants.
The only time I've known any smell to hang around was when some had been
used in a closed greenhouse on a hot day :-(

Comfrey is equally as good as nettles for the same job and it carries
less smell. Or you can use a mixture of both leaves.
