In order to publish your articles/posts on Fun Sci Club, you need an admin to appoint you as a writer. If you have something to tell, something to share (you do not have to write your own article, you might just want to share something existent, linking a source? If I was to write my own article each time I post, hah), then you just have to make an inquiry here, or notify me or another admin by any way, relevant to you.
Fun Sci Club - is a science-entertainment portal with quite broad spectrum of subject matter, thus articles/posts can be of various topics (just take a look at the existing articles/posts and their respective categories).
