Free-form musing here, nothing actually meaningful expressed or implied!
As the list of the forum users is sorted by number of posts, while browsing it (just for fun, some spare time...) I noticed that at page 43 occurs the last member who posted anything and then 55 pages follow listing members who registered to the forum but never posted anything.
55 pages out of 98 is more than half and this seems to imply that more than half of the forum users (i.e. more than ca. 1500 out of 2913) took the trouble to register themselves without having anything to post. As the fora are fully readable without any need to register, I wonder why this happens so often.
