year totals -- for groups and posters: are not the sum of the column. The totals are the total number of groups posted to, and the total number of people posting for the year
Prolific posters
This table is shown if there are enough posts
poster -- name of world member who has made a prolific number of posts
%total -- the percentage of the total posts they have made
Public posts vs world totals
Web-public -- The counts show only the statistics for posts that are published on this REBOL.org archive. The world may have many other groups and people posting. You can see those posts by joining the AltME world.
Questions
Why are some poster names shown as [unknown n]?
They are people who have left the world, and their name is no longer available.
Why can't I get your stats numbers to match the actual posts I can see?
Many reasons, some are:
timing -- posts are uploaded the archive once or twice a day. So it is seldom exactly in sync with the world as viewed from AltME
caching -- some of the stats counts are cached, and only update daily, regardless of when we upload new posts
philosophy -- should we count empty posts or those with just a smilie? Your answer may vary from ours, and ours has changed at times too
deletions -- a very few posts have been deleted (or not uploaed) to the archive; you may be seeing them on AltME itself
change of definition -- a group may have been [web public]. The archive will show and count posts up to the change. The AltME world will show all posts
stupidity -- there's been a few bugs along the way
apathy -- we could go back and address all the issues so you can properly reconcile the counts you see. But it's not going to happen
Why did the numbers change for an old year?
Probably because we have started publishing an old group, and all its messages have now been uploaded
Failing that, one of the reasons given in the previous question
