I trying to understand this command.

useradd -m -G accts -c "Name of User" "LoginID"

Add a user, -m = Create the user's home directory, -G = A list of supplementary groups which the user is also a member of., -c = What this one do?

Look at man useradd. From there we have:

Code:

       -c, --comment COMMENT
          Any text string. It is generally a short description of the login, and is currently
          used as the field for the user’s full name.

So that is why I need the the "".
useradd -m -G accts -c "Name of User" "LoginID"

When I typed: useradd -m -G accts -c John Brown brown I got an error. I should only need "" around the user Name and not the user LogID right?

Right, unless you have blanks or other special characters in he LoginID. (Not recommended, but not, I believe, forbidden. It could, however, really make creating backups hard since, by default, dump does not understand special characters in file names, and the LoginID is used as the users home directory name.)
