Is there a way that I can get a hard copy of the journal?

No. To see the articles published by the journal you can visit our website.

Is it OK to simultaneously send a paper to various journals?

No. This is against the codes of COPE. If one does so, his/her article will not be published. In case it is already published, the article will be retracted. Then the name of the author(s) will enter our blacklist and no manuscript will be ever accepted from the author(s).

Do all the authors have to register on the website?

No. Only the corresponding author needs to do so.
