I’ve been working on this one for a long time it seems. I shipped it to Denver for my long lost friend Aul, originally from Tallin, Estonia. We used to write to each other on Fidonet‘s InterUser in 1992-1993. Recently I picked up a book where I had logged all the node addresses of my best Fidonet buddies and started Googling them. I remembered the names of most of my buddies but sometimes forgot how they spelled it exactly. I found that Aul had moved to the US. Aul is a brilliant mathematician and chess player. We have always gotten along well. Aul has Spinal Muscular Atrophy (SMA) Type II therefore it’s complicated for him to get around. I will try to make it to Colorado to see him in the next few months.
