Help using UNIX systems!

[wizzz]

Hello people!
I'm using this unix system and I need some help.

[1]
Currently, I'm using PINE as my news group reader but it is basically not a good news reader. So I tried using ELM and it was totally unacceptable. I tried TIN but it doesn't have good interfaces. And it's annoying too.
So can anybody tell me a good news reader I could use in UNIX Systems?

[2]
In UNIX systems, to view a file I use the command "more [filename]" or "less [filename]". But after the file shows on screen, I need to press the spacebar to view the next page of the file. Is there any command or a program I could use so that when I open a text file, I can press the "down arrow" to scroll down line by line?

[3]
In some UNIX systems, when I press "emacs" I can use emacs on my terminal window. But in some machines, this command gives me some error. When I get the error, does it mean that the machine does not have emacs installes on HD?
Also, when I can use emacs on my terminal window, the "delete" button must be used to go "backspace". When I press "backspace" it is some other command. So is there a way to reconfigure the key functions so that the when I press "backspace" it actually goes "backspace" ?


I know these are a lot of questions but any help is appreciated.

[1] I use netscape news reader. Tin is ok.
[2] use a text editor, like pico, vi, vim, emacs, xemacs, ...
[3] if you type emacs and it gives error saying that command
not found, it might be your path is not set up right.

To make backspace = delete, type the following :
stty erase {press backspace here}

Don't type the { and } btw

I can use my backspace in my terminal.
but when I open emacs on my terminal, the backspace stops working and I need to press delete.

Does emacs reconfigure my keyboard functions?
What do I need to do in emacs to make the backspace work?

Any help is appreciated.

btw, vi is way too hard...
I wanna learn it but don't have too much free time.
