I was under the impression that it would also be "The effect of the black belt's punch was noticable", and you would have "the target was severely affected by the black belt's punch".
Or indeed "I effected a change in the structure of my company", just to confuse matters...
one spelling thing that just annoys me for some reason: loose does not mean the opposite of win! My shoelaces are loose, thanks to my poor quality shoes i always lose races.
Similar to "lose" (opp. of win) being written as "loose" (opp. of tight), "to" is often put instead of "too".
"Too" indicates excess or "also" eg "too much" or "Bill came too" or "I had a banana, too"
Another one is "its" and "It's". The apostrophe that normally indicates possession does not apply to "it". Including the apostrophe means "it is" or "it has". Technically, I guess you could write "its'" (apostrophe after the s) to mean itself but you would lose (not loose) friends.

Coofftopics are a pain for everyone.
"How are you Bob?" is incorrect; a coofftopic should follow "you". Coofftopics are easy: if the words don't make sense together, put a coofftopic in (eg from above: "you Bob" "together put").
