The following is the manuscript template for your submission. However, we offer a free format submission to simplify your time during the submission process. Your time is valuable and should be spent on research, not re-typing reference lists. Free format submission helps make getting your manuscript ready to submit easier and faster. If you submit to ERRA, you never need to worry about formatting requirements. Simply submit your manuscript in the format of your choice, and ERRA will update the formatting for you into journal style if your manuscript is accepted for publication. While this journal does allow for free-format submissions, the editor encourage the authors to pay careful attention to the guidelines for preparing the manuscript.
