Bert has just been busy with other things and has taken some time off, since April or so. I saw him in April at the Reno Show and he was fine. Life has a way of doing that. However, nothing to worry about.
He was having trouble logging on and said he would not be back, which is a GD shame. He was a pricless resource, really. I know he hangs out on some Winchester collectors forum and could be found through the Cody Firearms Museum website I'm sure. But I don't look for him back here.
He could log in, but his nose is twisted seriously sideways and that may be interfering with his keyboard. His last post thouroughly lambasted the Gunboards owners while they were struggling to make that last software work. It's a shame; we all hoped for broad minds and support while the changes were going on. And yes, Bert was a very valuable resource.
