hi again,

well, turns out there was a nasty bug for folks using Listen and 
Membrane/Remember together, where any attempt to look up the member id for a 
given email address failed.  this has been fixed and the 0.7.1 release is now 
available in all the usual places (i.e. on pypi, in plone.org/products/listen, 
and as a tag in the collective svn repository).
