List membership over time

The graph below shows how ``clarissa'' mailing list membership waxed and waned over the period Jul 95 - Mar 96.

Sorry, I don't have a text-only version of this graph.

You can get a list of the e-mail addresses of current ``clarissa'' subscribers by sending the single-line message

who clarissa

to Majordomo@tcp.com. The subject line doesn't matter.

If you have old lists of subscribers -- especially from sometime before mid-1995 -- please let me know so I can add to this page.


The raw data looks like this:

Here ``day'' represents the number of days since the founding of the list (i.e., 2/17/92 = day 1); ``since'' is the number of days since the last entry; ``members'' is the total list membership; ``diff'' is the change in total membership; ``join'' is the number of members who joined since the last entry; ``left'' is the number of members who left the list since the last entry; ``rdiff'', ``rjoin'' and ``rleft'' are the rates of change (in members per day) corresponding to ``diff'', ``join'' and ``left'', respectively -- that is, ``rdiff'' equals ``diff'' divided by ``since'', and so on.


Now for the plot:

[pic]

Note that the bars represent ten-times the rate of entry or exit. (Of course, the ones above the zero-line represent the rate of joining; the ones below, the rate of leaving.) I did it this way to make it easier to see the differences between the bars.

Note: All of this information is based only on e-mail addresses. It doesn't take into account that some members subscribe under more than one address, that they sometimes change addresses, etc.


Most active list members

This is information about the most active members of the ``clarissa'' mailing list, from its first month of existence, Feb 92, to Mar 96.

For each month, the total number of list messages (``mess'') and the number of members who posted (``post'') are given, along with the three most frequent posters (unless there was a tie for third-place, in which case there may be 4 or more for that month), the number of posts they made and the percentage of the month's total that their posts constituted.

month   mess  post  3 most freq. posters = # posts (% of total)

Note: The information above is based on the list mail as it currently exists in the archives. There's always a chance that some messages were lost. Also, I may have miscounted here and there -- especially for the total number of posters, for which I tried to count people, not just e-mail addresses.
