csh doesn't have one.  The easiest thing is to give the users .login and .cshrc files that
source your system-wide ones, though that risks users editing them out.

Of course, if you have source code, you can change csh to use a system-wide file.  I've
seen it done; the changes are minimal.

You do something like

	echo -n "Type something interesting: "
	set foo = ($<)

$< expands to a line of input.

MIT's Project Athena used the scheme of first initial, middle initial, plus the
last name (if 6 characters or fewer, the first 6 characters if not).  This generates
some interesting usernames, but they are almost always unique.  They are
generally easy for the user who owns it to remember it, but it's often non-mnemonic
for someone else -- although the VMS scheme is less mnemonic for both, I would think.

Good luck with it.
