I heard at the weekend that Richard Biggs, probably best known for his performances in "Babylon 5" as "Dr. Franklin" passed away at the age of 43.
I only met him at conventions, so cannot in any way claim to have known him well, but from what I saw of him suggested that he was, indeed, 'a nice bloke'.
Not that anyone from his family or friends will probably read this, but I offer my deepest sympathies to them for their loss.
Apparently, some of his friends and former colleagues are working on something to help his family - as and when details of this are available, I'll post them here.
In the meantime, there is a tribute page on the The Gallactic Gateway
