The original thread about Tom's situation was focused mainly on collecting suggestions and information about possible ways to avoid a worse case outcome. Of course many of you also sent messages of condolence.
Stoat has suggested that a new thread, focused on condolences, is appropriate and I agree. If you have already posted such a message in the other thread please feel free to repeat it here or to post another.
Due to limitations in the forum software it is not possible to move messages around or to make an exception regarding the need to be registered to post. If anyone would like to send a message of condolence but does not want to register please send me an email and I will forward it to Tom's family. I will also post it to this thread unless you ask me to keep it private.
