How to create new user?

Is there a built-in program to add new users and setup the /home/.<user> directory. Since the dcopserver took a dump (failed) on me I'd like to create a new user account/dir to use. Any suggestions or HOWTO's? P.S. If someone can tell me how to fix the dcopserver, since now the /home/curtis dir is now the /home/curtis file (what used to be the dir /curtis is now a file 'curtis'). I would like to fix this because all my /home/curtis directory was setup the way I liked it. Thanx, Curtis Rey
