Chris or Kim,
Chris, regarding the never ending pages - you said "Somewhere in all those posts, there is one that didn't finish correctly and it causes that. Finding it is like a needle in a haystack and after that, then the problem of editing would start."
I have noticed just this week - that a couple of times in a reply, people have "changed" the subject... does that have anything to do with it? I thought the ability to change the subject box had been disabled some time ago to prevent the problems it creates.
