its up to you.. it should have at least the name '42coin' attached somewhere... and maybe make it unique so it appears better in search engines like... '42coinblog.de' or '42coinNews.de' just make sure 42coin is there for search engine purposes and also the community manager must be able to properly manage threads. Also, for germany we do have coinpools.de working on it, so maybe you can just stick to writing content for 42 in germany online on your own domains?
