That tag is pretty lengthy and a new one gets appended to your reply anyway. It's not uncommon to see a message having several footers at the bottom because people forget to crop them off. Other subscribers feel the same way, that is, about the title, not the tofu. I don't know or care if they love or hate tofu. If you find your reply changes the subject matter, then take a moment to change the title.
People subscribe to a list for the topic intended.
It's okay to go off the beaten path once in a while, but should the thread live too long it defeats the purpose of the list. The listowner can and will kill a thread if it doesn't meet policy. Don't be offended if this happens- this mailing list generates a lot of traffic and whatever gets discussed should relate to the list topic. DO NOT send SPAM, advertisements, urban myths, chain letters or the like to the list. SPAM is punishable by being banned from the list, period.
