It's so I can proofread what I just submitted and see all the spelling errors I missed.
That, and to see if someone else snuck a post in while I was typing with three fingers.
All forums on the internet are set up that way.
Well its pointless for you if you are looking for spelling errors because you cant go back in and change it once its submitted
You may want to get the software that types while you talk if you are only using 3 fingers LOL
I'd probably develop a lisp or a speach impediment.
Or my computer would crash.
I've got 9 1/2 fingers, but only three of them know how to type.
Actually, it's 8 fingers and a thumb and a half...but most of them are illiterate.
