diogenes: It wasn't me who started to write with exclamation marks, capitalized words and similar unfriendly attributes. I always try to explain everything in peace but when I see someone could ruin my work for no logical reason (and I'll be glad to know I was wrong), I have my right to protect myself.
Btw, if the site would be to money oriented, I would never respond.
There are many things which I have to see from much more complicated point of view than a normal user can see. And since a day has only 24 hours, there are many situations where I prefer to say "no" shortly, instead of starting a complicated discussion.
