I've just had another look at the "Bitter Lemons" thread and there are no posts missing ....
It was providing quite a lot of amusement, with no one attacking anyone and I must say it remains one of the most surprising locks ... perhaps it was a mistake?
I am not arguing, (just curious and perplexed) ... but the most powerful tool Admin possess is surely to delete posts or transfer threads to another section.
Locking them prevents the free-flow once a thread gains a following and "warmed up" threads can be the most interesting.
Besides another could be opened in its place to carry on, but it takes time to gain an "atmosphere".
Again, I hasten to add I am not complaining, just heightened curiosity and interested in analysing decision making, and thread growth and evolution.
I wholeheartedly support the deletion of offending posts however.
