delete messages

I have an unset message that I just want to delete, but the only option is to "send now". How do I get rid of it? I have tried, but no success. Hope someone can help. Thank you

I am currently having problems with deleting vistor messages. I have done a search and checked tutorials but could not find any similar problems, except mine. Could someone tell me how to report this problem and to whom? Or point me in the right direction to find the answer? Thanks, David
