Firstly, it seems that I covered for RobinJB during his Shanghai abscence, as Oct 2003- Jun 2004 was the period where I did most of my posting!
Secondly, there is a feeling (well, with me it is) that I've run out of things to talk about with regards to Knightmare.
Thirdly, and related to my second point, most people have seen up to all the 8 series of Knightmare on Challenge, taped them, and can watch them forever and ever and ever (and only wince at slightly foolish voice-overs). People have had their hearty Knightmare fix, and it's unclear whether a cycle will occur, when people will re-rediscover Knightmare at a later date. Huge amount of credit to Challenge, though. Without them this forum would be more barren by now, I believe.
I belonged to a forum of schoolfriends, and after we all left that school in 2003 the post count of people gradually dropped over the summer, then people went to University, and by mid 2004 there was no-one left. The glory days of 2002 (and many debated that I look back on and think 'whoa!') were gone.
That's my fourth (and to your relief, final) reason- that we're just getting older, and some of us have other commitments, whether it be work or University.
Man, that's a little depressing. Still, the fire's not burnt out here- not by a long shot!
