It really was predominantly the need to move on from all things JW and the feeling that if the site was still up he wouldn't be able to move on. And yes, a few members engaged in behaviour that was very wearing for the whole team. I think that was the straw that broke the camel's back.
Rifter had obviously been dwelling on this for a while even though he only gave the rest of the admin/mods a few days notice. And yes I appreciate that's more than the rest of you got. I did not think it was my place to go against his request and announce the forum was closing and given that everyone else was in the dark it felt inappropriate to me to start a personal goodbye thread so I kept quiet.
My sincere apologies for my part in that.
