A friend of mine is a researcher with extensive experience. To get to where he wants to go, he has done a lot of research, tried a lot of things, and found solutions to problems that people face every day. He is unaware of the procedure for creating or updating a Wikipedia page. I mentioned this professional Wikipedia page creation services to him when we last met because I had also heard of it but wasn't sure about it. Who has taken services of professional Wikipedia page creation before?
