Is louiswu actually Michael Ries?
I tend to check domain names with whois.com because one can glean information as to evaluate sincerity or lack thereof. Even when registrar privacy is invoked, as nameserver info can also indicate where a server is hosted. This is not to dox, but to examine “who is” when possible. Not just for this message, but for a variety of messages. Promoting one’s self through this marvelous forum seems rather a cheap shot. Ditto with daily promotion of one monetized site or YouTube channel.
