If you only do this project to learn more about programming, it definitely does not belong on sourceforge!

I'm all for reinventing stuff. I have both the ``Not Invented Here'' and ``Let's Reinvent the Wheel'' syndromes, but I can still think of a few objective reasons as to why it may be beneficial to roll your own applications in general, and text editors in particular:
- You can implement exactly what you want in exactly the way you want it
- You can leave out tons of bloat included by other text editors that you never need and use
- Since you are the author, you will find it very easy to add new features and bugfixes. This may be a lot harder with a huge and unknown source base of, say, emacs
- It will help you become more familiar with text editing in general. The console version may provide new insights about terminal capabilities and the terminal databases to begin with ...
Oh, and
Don't you think there are even more ``ls''-style programs than Unix text editors?
I have started writing the source code, so there is source.
Just because there are many text editors doesn't mean that I should "re-invent the wheel."
-------------------------------------
I have a question to ask a few people.
Should the program run on an X11 server (like Ted, the Linux RTF editor), or should it be a program that can run on KDE (like Konqueror)?

TALK(1) BSD General Commands Manual TALK(1)
NAME
talk -- talk to another user
SYNOPSIS
talk person [ttyname]
DESCRIPTION
Talk is a visual communication program which copies lines from your terminal to that of another user.
Options available:
person If you wish to talk to someone on your own machine, then person is just the person's login name. If you wish to talk to a user on
another host, then person is of the form 'user@host'.
ttyname If you wish to talk to a user who is logged in more than once, the ttyname argument may be used to indicate the appropriate terminal
name, where ttyname is of the form 'ttyXX' or 'pts/X'.
When first called, talk contacts the talk daemon on the other user's machine, which sends the message
Message from TalkDaemon@his_machine...
talk: connection requested by your_name@your_machine.
talk: respond with: talk your_name@your_machine
to that user. At this point, he then replies by typing
talk your_name@your_machine
It doesn't matter from which machine the recipient replies, as long as his login name is the same. Once communication is established, the
two parties may type simultaneously; their output will appear in separate windows. Typing control-L (^L) will cause the screen to be
reprinted. The erase, kill line, and word erase characters (normally ^H, ^U, and ^W respectively) will behave normally. To exit, just type
the interrupt character (normally ^C); talk then moves the cursor to the bottom of the screen and restores the terminal to its previous
state.
As of netkit-ntalk 0.15 talk supports scrollback; use esc-p and esc-n to scroll your window, and ctrl-p and ctrl-n to scroll the other win-
dow. These keys are now opposite from the way they were in 0.16; while this will probably be confusing at first, the rationale is that the
key combinations with escape are harder to type and should therefore be used to scroll one's own screen, since one needs to do that much less
often.
If you do not want to receive talk requests, you may block them using the mesg(1) command. By default, talk requests are normally not
blocked. Certain commands, in particular nroff(1), pine(1), and pr(1), may block messages temporarily in order to prevent messy output.
FILES
/etc/hosts to find the recipient's machine
/var/run/utmp to find the recipient's tty
SEE ALSO
mail(1), mesg(1), who(1), write(1), talkd(8)
BUGS
The protocol used to communicate with the talk daemon is braindead.
Also, the version of talk(1) released with 4.2BSD uses a different and even more braindead protocol that is completely incompatible. Some
vendor Unixes (particularly those from Sun) have been found to use this old protocol. There's a patch from Juan-Mariano de Goyeneche
(jmseyas@dit.upm.es) which makes talk/talkd, if compiled with -DSUN_HACK, compatible with SunOS/Solaris' ones. It converts messages from one
protocol to the other.
Old versions of talk may have trouble running on machines with more than one IP address, such as machines with dynamic SLIP or PPP connec-
tions. This problem is fixed as of netkit-ntalk 0.11, but may affect people you are trying to communicate with.
HISTORY
The talk command appeared in 4.2BSD.
