Changing 'sitename' for all users

["karenhowie" <webforumsuser@xxxxxxxxxxxxxx>]

Hi folks,

 Sorry to bother you.  I am an administrator of a number of sites which I 
inherited.  We have a lot of Contribute users who have access to different 
degrees to the various different sites (on different servers).  However, the 
sitenames (which I guess are generated by contribute via the index page title?) 
did not make much sense and I've now tidied them up so that the title reflects 
more about what the site actually is. (Tried with first site) I was hoping that 
this would update how the site is referred to for contribute users, but the 
sitename remains the same.  I've edited the contribute.xml file for the site on 
the server, cleared all of my keys and generated myself a new key but it is 
still the same.  It is wrong in the actual key file even after it has been 
regenerated/resent and the only way I can see round it is to edit individual 
key files (.stc) but I don't want to have to edit this file for everyone I send 
a key to..... any thoughts?  Have I missed something?

 many thanks!
