OK, I may not have made the statement clear enough. the reference to /user/ was ment to be your user name (which is often, but not always, the name of the home directory), you mentioned that your home dir is in root, hence it should be off of / as shown. But to help eliminate confusion, I am going to ask you to log in as your user and from the command line type:
The first of the above should take you to your home directory. The second will display the 'present working directory', which will be your home directory. Assuming that you have rights to this directory, you can take the output from pwd and run it through the chmod command mentioned above...
chmod -R 777 <insert output from pwd statement above>
the chmod command will allow you to change the persions to a file or folder, the -R informs the command to apply the calue recursivly, anf the 777 sets the persions to 7 (read, right and execute) for the owner of the file the members of the group for the file and everyone else.
