Because, as the old saying goes, "on the internet, nobody knows you're a dog".
Who are we to know what kind of person you are when you come here as a newbie,
asking for a 1W laser?
You might be the Pope, trying to get God's attention with the help of his new Arctic, or you
might be Osama, trying to crash some more planes
for all we know.
The only way for us to trust the newb, is for the newb to contribute to this site.
Be it with pictures of his own builds, be it with thoughtful comments.
Over time, the newb will gain our trust, and cease to be a newb. OR NOT!
I'm terribly sorry, but for the sake of safety, I
must consider
everyone who's 1st post is:
"I wanna 1W LAZOR, NOW!"
to be a 12 year old kid who wants to be Darth Vader.
Not that there's anything wrong with WANTING THAT, but if I did anything else than
advice him to buy a 650nm, 532nm, 405nm "5mW" from ebay instead, I would
be a terribly irresponsible member of this community.
