I thought I was usually pretty nice.  Must give you an idea how
sarcastic I can be in real life, eh?  :)  Maybe I'm just too curt.

But in reality I almost never answer RTFM questions, because I 
know dozens of other people will.  Surely you're thinking of one 
or two specific responses; could you email me with the ones you 
have in mind?  I'd hate for people to have an allergic reaction
to my ascerbic personality.

How about doing some adjustments on this example?:

//BEGIN
#declare rLED=
object {
sphere {0,1} //shape only (replace with yours)
 pigment {rgbf<1,0,0,.5>} //lower or raise filter amount
  normal {granite .025 scale .025} //reduce further if grainy
   finish {ambient .75 diffuse .1 phong .5 phong_size 5}
}

light_source {0,
 color rgb<1,0,0> //change 0 to location vector if placement needed
  looks_like {rLED}
   fade_distance 2 fade_power 2 //make distance fully lit maximum
}

camera
{
  location  <0.0 , 0.0 ,-9.0>
  direction 3*z
  look_at   <0.0 , 0.0 , 0.0>
}

plane {y,-1 rotate -15*x pigment {rgb 1}}
//END

I'm guessing this question has already had many answers but I forgot by
the time I finished reading the follow-ups. Wonder if a chat-like
newsgroup is feasible? :|

If I did, then I apologize. (I like this about new.povray.org - everybody is
so friendly, you don't even need a killfile :-)

Nope - as you can see, I didn't answer to the original question - mainly
because others had already answered when I read it, but I guess I wouldn't
have even if no answers had been given yet, because of the lack of time and
the confidence that in this special subject others would come forth with the
same answer I would give (high ambient value).
I must concede: Had I known more about the content of the VFAQ than I
currently do, then I would probably have answered with a link to it. Maybe I
*should* read it again :-)

Greetings,
Johannes.

Perhaps the reason no one is using the VFAQ is that they don't know about
it......I've never heard of it, but everyone is so busy bitching each other out
that no one has posted the URL so I can get it. To tell you the truth, it sounds
like a good idea, and I'd love to have it, so could someone please tell me where
it is?

This is the permenant but temporarily off line link:

This is the temporary link to the VFAQ

Ahh, so the sig is C code?! I thought my newsreader was missing something...
OK, so I'm slow, I don't know C and I missed the joke :(
I GOTTA learn C, dammit!

  All this is ok. I didn't mean to blame you or anything. I understand
what you mean. :)

  I remember a funny Garfield postcard which says: "Feel free to waste my
valuable time".

Why don't you organise (organize) things such that the first time someone posts
to this server, they get the VFAQ mailed to them ? As long as it's only once it
shouldn't be an issue (if it's big then perhaps only mail them the location).

This would have to be done at least partially manually due to despammed email
addresses, but the rest could be automated.
