I am wondering if the i changing into I is, in any way, due to the person having "auto-correct" or similar switched on. The letter i typed on its own, would then be automatically altered to I (to make the sentence grammatically correct) Perhaps someone could try and see whether this works by switching off their auto-correct.
I wish I knew where it was rusty. I remember only switching it off (somewhere) when I was trying to send a solution to jolan's 5@5 and the blooming thing kept altering my answer.
Not to worry, Jazzgirl.
I don't think I have ever used it, (where ever it is)
That was an excellent point you made about being grammatically correct.
You may be on to something.
