Argh!!!!

As a newbie admin, I really have a tough time with permissions. I  
swear I got a permissions error when I tried to delete this dang  
file, but I just logged in as B and was able to delete it just fine.  
Of course this is because B owns the directory.

I guess I must have done something boneheaded an hour or two ago...  
gosh, I hate wasting time. Mine, and the lists, of course.

Well, thanks to Valintin, I did figure out how to change the umask  
for pure-ftpd. So now uploaded files have the permissions I wanted,  
even if they are not needed.

And thanks to the rest, I figured out it was working all along... And  
now I can't even duplicate the error I saw before...

<sigh> Does this ever get any easier??? How can any one person  
remember all this stuff???
