Glad that you find him excellent. He blocked me unexpectedly when I first began to reach out to people just before the pandemic. Perhaps as a complete newbie I wasn't brief enough and wasted his time. I'll never know since there was no opportunity to set things right because his profile was suddenly 'inaccessible'. Oh well, apparently my loss. I wish him well and regret whatever I did that offended him, but I'm also glad that he blocked me if that is his approach with people who have very little to no experience reaching out.
