Roles of Editor:
1. An editor receives a 'problem statement' and its solution from the coordinator or senior editor.
2. If there are any sub-editors, the editor forwards the 'problem statement' and its solution to the sub-editors. In this aspect, the editor assumes the role of senior-editor for the sub-editors.
3. The senior-editor collects the editorial input: errors and possible suggestions, from the sub-editors and integrates them along with own input and prepares a summary and forwards it to the senior-editor or the coordinator as the case may be.
