I see you've never used this version of Pnews before.  I will give you extra
help this first time through, but then you must remember what you learned.
If you don't understand any question, type h and a CR (carriage return) for
help.

If you've never posted an article to the net before, it is HIGHLY recommended
that you read the netiquette document found in news.announce.newusers so
that you'll know to avoid the commonest blunders.  To do that, interrupt
Pnews, get to the top-level prompt of [t]rn, and use the command
"g news.announce.newusers" to go to that group.
