My double spacing is prob even more annoying to me , than to others :
I've said on the boards before I have dyslexia , and if I don't double space I lose comprehension.
It's something I have to live with. Makes life quite difficult : trying to read the paper etc.
Actually I was quite grateful seeing other posters picking up this style/habit of writing recently.
And to top it off , I'm blind as a bat
Not perfect , after all
