hey guys, using MS Sharepoint Designer, i incorporated Muellmann's edit [thanks!] into an updated xml and it's working fine in vB 3.6.8 PL1
this will do as Paul described but it won't delete ALL of that member's ratings from ALL threads....only that particular thread.
if u already installed it, then just overwrite the product with this one.
many thanks to Paul for sharing this useful addon.
and apologies if this was wrong of me to share here.
