Hi,
Just a small thought on the side before DW gets to this.
It seems strange that people won't click the !remove link in your mail.
I have just received some mail (not from you though) and I often don't get remove links although the senders are sure to put them in..!
In these particular cases they send from one of the agencies (I think) in HTML but I only ever read mail in text form. It seems somehow that if people send HTML mail and they get read in text, in some cases the remove links don't get put in.
It has always seemed strange to me as the other links are in the mail. Maybe in my case its something to do with how they convert and that the !remove links are from tags but the links I get are the ones they directly type in.
Just a thought, anyway.
