I'm sure they will start posting again when they are up to it. It's a terrible loss for the bandmates who often spend day in day out for weeks on end with eachother, then suddenly one of them is gone. I'm sure it's like losing a brother who you spend a lot of time around. It's alot to get ones head around.
There are a few things more important going on, and dealing witht he loss of Mike is only just the beginning, 'cause there are many other things to consider. Not slamming you Alteredmindeath, but really, was this thread really necessary, put yourself in their shoes, would you want do some minor thing like post on a forum at the moment?
