I have no problem with a YouTuber, Podcaster, Author or Homebrewer sharing their work as long as they interact and aren't constantly making multiple, needless threads simply to self promote.
That is exactly our feeling. No one is going to be asked to leave for posting videos of anyone on YouTube or about a book or homebrew. We post videos all the time that are pertinent to topics or that may generate discussion, so that is not an issue. You are, of course, welcome to stay and continue to post but what we are asking for is to contribute also in the forum in general. I hope that clarifies your concerns. If not, let us know either here or by PM. Thanks.
