This has been talked about before, and the concensus was a linked list of
id nums. That allows for dynamic expansion of the list to add in new
introductions.
The only problem that I see with this, is that after a character has been
deleted and a purge has been run on all the deleted characters, their id
nums will then be available for new characters. I can better illustrate
the problem than describe it.
Bob introduces himself to you. (idnum = 5)
Bob deletes.
Immort kills the mud, runs the purge to free up spaces, and restarts mud.
Joe makes new character and gets idnum 5 because it's now free.
You now know Joe automatically because his idnum is stored in your list
of known characters.
There needs to be some method of removing someone's idnum from all
characters list of known characters when they delete.
