[SuSE Linux] Why cant people on mailing lists read?

Dear diary, I have often wondered why people who can't read subscribe to mailing lists. I have never heard of any list, where you unsubscribed by sending to the list itself. Additionally, I have never heard of any list, where new subscribers did not get an e-mail with instructions on how to unsubscribe. And especially on this list, where every mail includes unsubscribe info, the only explanation for the many "unsubscribe", "remove" and the like _must_ be that the people sending them simply _can_not_read_! My question then is: If they can't read in the first place, WHY do they subscribe? Yours Ole - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
