Nothing will be deleted; the intention (expressed by several users) is that this should remain as part of the historical record.
I therefore propose to let it run on for another few days, and then turn the community over to moderated status sometime next week - new posts will only be added if they provide something that is factual, opinion-free and NOT available in the mass media.
If anyone has a radically different view on this, please comment - although this was the approach suggested a couple of days after last Thursday's events.
I hope the community has been useful - it seems to have provided a lot of first-hand and reported information and given people ways of getting in touch with friends/family etc.
Just as an admin note - I will be mostly AFK from tonight until Monday morning, so could the other members of the maintenance team keep an eye on things over the weekend? Thanks.
Thanks once again
