He is the problem.  I assume it's because he thinks he's a dog, cat or 
some other animal.

As far as I can tell, you're being asked to change that to your “real”
name, whatever that is supposed to mean.

I recommend you ignore that request; “Bartc” is fine as a name here,
IMO.

Given that LARTC means Linux Advanced Routing and Traffic Control, I'm
guessing Bartc is all about *BSD networking? :)

I thought LART were the Luser Attitude Readjustment Tool ;-)

And on GABELNs [1] it is considered polite to post using your real name.  
Lack of politeness towards the people whom would otherwise be willing to 
help you may cause you to be ignored by them instead.  You have been warned.

BTW, it’s attribution *line*, _not_ attribution novel.

Falsehoods programmers believe about names:

> You have been warned.

And you should consider the irony, and hypocrisy, of somebody who signs his
posts "PointedEars" bitching about supposed "real names".

How do you propose to tell the difference between "real" names and "fake"
names? If BartC signed his posts "Engelbert Humperdinck", "Cher", "Thomas
Lahn" or "Bartholomew Roberts" how would you decide whether it was "real"
or "fake"?

Petty bigotry over "real" names is no better than any other sort of bigotry.

TPEL has been trolling html, php and javascript newsgroups for years, 
recently he seems to have discovered python newsgroups. :(

I found that TPEL post to be particularly amusing/ironic (hilarious, really) when he continued 
by talking about a group that ignores posts by people who don't use real names!   :-)
I generally ignore his posts as well.

      -=- Larry -=-     <-- My real name, which is NOT Lawrence (or anything similar)!

I'm reading this 'list' on usenet. No-one else in many thousands of 
posts has ever complained before about my user-name.

But I guess you haven't been on that many forums. Few people use their 
full names or anything that looks like a real name. Partly, so they 
don't have someone who violently disagrees with them causing problems 
(like discovering their address and coming round).

Mostly people use names that are wacky, funny, or just meaningless.

(FWIW, my real first name is Bart and C is the initial of my last name. 
Very dull I know.)

That's a common way of signing emails. I sign most of mine "ChrisA",
which (as you'll see from my headers) is constructed the same way. So
did the late Dave Angel (DaveA). Although I suppose I'm going to get
in trouble with PointedEars for not using my *full* name, but
abbreviating it to just "Chris".
