Ooh dear, hands up!
I've always been very lazy on here, typing using all lower case with the lack of apostrophes.. tut tut..
But, I'm now doing my bestest to do it right!.. when I remember!
However, with anything else, I always write in full and am very particular with presentation and punctuation, etc..
I type as properly as I can, except that I usually leave the first letter of a post on AB lower case, I forget why. But for search engines where it doesn't matter, I don't bother. (Because I am forever bumping the caps lock key when I just wanted the shift key, and ending up with EVERYTHING IN CAPS LOOKING UGLY).
