Hello Pat,
Very sorry for this. Please be aware that Contrebombarde is a separate site from Hauptwerk and run independantly from Hauptwerk. These issues are not able to be taken care of by us at MDA and should be discussed directly with Classic Organ Works as they are the ones who run that site.
Also these issues would best be sent directly to them via email rather than on the Hauptwerk forum.
I'm sure they will be able to fix whatever problem it is they are having with spammers.
Thank you and I hope they are able to do so.
