When you change the list parameters for subscription options it does not affect those already subscribed, so those would be the Topics= None. Topics=All would be new subscribers (maybe also those who set themselves nomail and then back to mail?). The ones with specific topics are your more sophisticated subscribers who have looked at the header, seen that you have installed the Topics keyword, and know what it means and how to change their options. Of course, that is rather futile on their part since you haven't announced the use of Topics so probably no one is putting the keywords in the subject line, so it's the same as not having Topics at all. For Topics to work the subscribers have to know about it and cooperate by putting the keywords in the subject line, or there is no point to it. Question for Eric: In the new LISTKEYW TXT the meaning of the "reserved" settings for Topic aren't explained. For example, what is the effect of having Topics= None in one's personal subscription options, rather than Topics= All ? Are the Topics settings linked to the Mail settings? And I'ld like to see an explanation as to why one shouldn't reorder the topics and leave a blank in the line if you take one out. If you install Topics and then decide it isn't working for your list, is there any problem with just deleting it from the header?
