Ok, let's have a look at what you need to do:
1. Add new connected state CON_Q_IFNEW
2. Decide on a login sequence.
3. Make new descriptors start in the correct mode
4. make nanny() handle the new con state.
5. adjust the rest of the login sequence.
Let's go through them one at a time:
1. too easy to spend time on
2. This is actually the most important step. If you do this right,
the rest is very easy. In this case, you've already decided on[1]
Race, Class, Sex, Name, name confirm,
/ Password, Password confirm, menu
/(yes)
new char ?
\ \(no) Name, Password, menu
\
\(no input) Disconnect
3. in comm.c - new_descriptor(), change the default state to CON_Q_IFNEW.
Search for CON_GET_NAME.
4. The new state should logically handle this:
if input is yes
start character creation sequence
else if input is no
start login sequence
else
disconnect
Mailer code:
case CON_Q_IFNEW:
if (!d->character) {
CREATE(d->character, struct char_data, 1);
clear_char(d->character);
CREATE(d->character->player_specials, struct player_special_data, 1);
d->character->desc = d;
}
if (UPPER(*arg) == 'Y') {
send_race_menu(d);
STATE(d) = CON_Q_RACE;
return;
} else if (UPPER(*arg) == 'N') {
write_to_output(d, "By what name do you wish to be known ? ");
STATE(d) = CON_GET_NAME;
return;
} else {
STATE(d) = CON_DISCONNECT;
return;
}
break;
End mailer code
5. The most difficult step, since it requires modification of current
code. My suggestion is stepping through the login sequence, one step
at the time (corresponding with point 2, above). Look at each step,
making sure you don't do anything you shouldn't be doing, and you're
sending people the correct texts and setting them to the correct
state. Be aware that since stock circlemud assumes a specific order,
it _will_ do things you don't want it to. For instance, if you are
creating a new character, and decide the name isn't what you want,
it calls free_char() which invalidates all other info already
stored in the d->character struct[2]. In stock circlemud there _is_
no such info. You change it, you make the code deal with it...
Good luck.

[1] It's a lot nicer (and quite a bit more complex) when written
on ordinary graph paper instead of ASCII art.
[2] I realize calling free_char() (case CON_NAME_CNFRM) is good for
memory. However, this seems a bit overkill, since the memory
will eventually be free'd anyway, if the character enters a
blank name the second time around. Wouldn't simply freeing
the name be sufficient?
write_to_output(d, "Okay, what IS it, then? ");
- free_char(d->character);
+ free(d->character->player.name);
STATE(d) = CON_GET_NAME;
(just a proposition)
