I've just glanced on ja606, nothing on there recently from Hawk that I could see, I do hope he is ok...
Hawk did disappear before for some time, but this does seem a longer period of silence, Lets hope will hear from him in the near future.
he did come back briefly and say he had been in hospital, but a week later? he disappeared again. I thought he mentioned he hoped he would improve and not need to go back for something more serious
