That's what you came up with? After two days? That you don't understand the
question?

You may have posted on the 25th, but your iffy news server didn't
deliver the message until today. Your posts often arrive late and in a
clump.

And invariably incorrect.

Yes. Often I see "30 new posts" and think clc must have fallen prey to a
splorge attack like the ones that have hit sci.math recently. But no,
it's even worse than that! It's 30 posts from CBF, mostly on stale
articles, and with a rough breakdown of
15 netnannying posts
10 posts that are completely wrong
5 correct but pointless posts about trivial and irrelevant details

Indeed. So very true. A nice breakdown of any 30 CBF posts.

The net nannying ones should be further broken down into posts which
break the very rules he professes to admire so much including topical
information in the signature, double signatures, overly long signatures
and advertising his own absurd C libraries and services as a contractor.

Wouldn't it be better to include the above in a sig block?

At least when they get to my news feed, your posts have no sig
delimiter. This is normally a line containing "-- " and nothing
else. There should be one here (after a blank line):

I've never used Free Agent, but perhaps you need to include the "-- "
line as part of your signature.
