             This message means that uni-SPF was not able to write to the file 
              SPFPROF.tbl in your $HOME directory. A common way this can happen 
              is that you have previously 'su'd to root or another userid, then 
              started uni-SPF. This will result in an SPFPROF.tbl file being created 
              in your HOME directory with a different owner. When you are logged 
              on as yourself, you are no longer able to write to this file. To 
              correct the problem, remove the SPFPROF.tbl file before entering 
              uni-SPF.  
			  
            Occasionally, we see this problem when more than one person is 
              logged on using the same userid. This is a dangerous practice, and 
              is not supported within uni-SPF.
