There is no obligation to use the RELP articles as references and citations; Editor and reviewers are not allowed to ask/ force the authors to use this journal articles as the source of citations; however, we would feel delighted if authors, by themselves, find our published manuscript useful and-up-to date  for their research and studies

The reviewing process is between 3-6 months (if authors answer in time and meet deadlines); and the papers are accepted of the reviewers and editors provide us with positive feedback. It must be notified that sending papers to reviewers is NOT considered an acceptance decision 

Yes, when a reviewer completes the reviewing process, one certificate is formed automatically for each reviewing work; this certificate can be downloaded in the reviewers' account
