To list those files, you need to use the -a options.

Normally, those files serves special purposes, like .signature is to be 
attached to your mails and news postings, .login is to be executed when
you login, whereas .cshrc maintains the list of newgroups that you have
un/subscribe and what articles you have read.  Normally, you wouldn't create
a file that starts with a "."  It's the machine's way of saying: hey, these
are my files, unless you know what you are doing, don't mess with them.

the chmod function allows you to assign permissions to different catergories
of users.  the 7 means that you are giving yourself read, write, and execute
permission.  The first 0 means that other users in your group cannot read,
write, or execute (add 4 to that number to allow reading permission, 2 for
writing and 1 for execution), whereas the last digit coresponses to all
users....

Not really hidden, just "protected."

One last thing, always make sure that your home directory is readable
and executable to all users so others can see you .plan
