I prefer not to receive private messages. If you really feel the need to send me one, please do so, but keep in mind that it's a form of communication that I find very difficult, so it will probably take a long time for me to respond. If the message generally shows low effort, it will probably never be answered. So the safest bet if you want to tell me something is to do it with open comments on my content, that way we can all participate and benefit from the conversation.
