I sometimes think that there ought to be a guide to reading Mudcat threads - something like:-

Posts 1- 25 Information exchanged, positions taken up
Posts 25-50 If discussions, continue they become more heated.
Posts 50 + Increasing appearance of posts simple given as 'GUEST'. Strong challenges to any stated position, insults start to be exchanged, withdrawal of most posters, combatants left to slug it out.

I ought to add, sadly, that this only applies to threads that are on British subjects and are dominated by British members of this most erudite and considerate of notice boards.
