Valerie, Tamlin's wife thought it might be helpful if I said something here.
I won't go into the the circumstances leading to Tamlin's current situation but his medical condition is improving however his spirits are very, very down. He does not have Internet access.
For those who do not know William (Tamlin) his generosity in sharing knowledge and CPs is legendary within this community. Pay it forward is his philosophy - pass on his generosity to others. Many of you may be the beneficiaries of his philosophy and not even know it. A fine tribute to Tamlin can be found on Terraforums in this thread.
Valerie has created a Facebook page Support William Tamlin Dawnstar. Read it carefully and decide for yourself if and what you can do to help.
The main thing you can do is to write to him and let him know he is not alone and forgotten.
