Hi!  I'm the listowner for Gardens and Gardening through the University of
Kentucky.  I have a subscriber who is getting her Gardens mail, but can't
post to the list.  The error message she's getting is below.  Is there
anything I can do to help her?  I'm not sure what's causing the problem.
Thank you,

Elizabeth Trotter
