More than that is hard to say just now. I think it will be a bit before I am coherent.
There is a post on Making Light.
Please pass the word to the people who loved him, liked his work, and so on. There will certainly be some sort of memorial service, but it won't be for at least a couple of weeks. Late October is the best I can give right now. More when I have it.
Hug your dear ones.
