Welcome! It’s good to see folks coming in from all parts of the world. Your background is impressive! No doubt that you will be a welcome contributor to this community. Don’t feel pressure to impress. Take your time to get a feel for the different styles of the people who post and the comments they receive. But do feel free to comment and share your unique perspectives when you see an opportunity. I am in the US and can benefit for hearing a different view of the world now and then. :)
