Because they hate when people miss the obvious.
What's obvious to you is not necessarily obvious to others, Remeber not all members are active as you are.
I know, besides it was sarcasm because my first post was not rude (in my head) I was just posting what was on the page and telling him that it should answer 1 or 2 of his questions and just reminding him where it is. If I wanted to be rude I'd say: Also since you overlooked it I'll just repost it here.
But I wasn't trying to be rude.
I know you didnt mean to be rude and I didnt think you were, I just wanted to point out the incorrect perception of the "obvious" that's all.
