Tho my search of of the web for archives using Mhonarc multipage reverse date order did not turn up much, I think this is a very useful format.  My ISP is just dealing with the bug by disabling such links :(  The archives of my main list has nearly 25,000 messages (about 125 index pages of 200 messages per index page)  See them via http://cohousing.org/cohousing-L

OPEN: The problem is that a listing for a message in a thread index is not "fixed" due to how threads are organized. Non-related messages can move the location of a message listing, but currently MHonArc is unable to detect this. A possible solution is to compare old ordinal location with new ordinal location for each message. If different, see if new position cause message to move to another index page. If so, mark message to be edited. This kind of check would cause a performance hit, but it may be unavoidable inorder to fix the
problem.
