I second your suggestion. I will be loved to be corrected for my English though I may not be able to help other people very much. I don't have anybody who can correct/review since I finished my college. If somebody can fix my habitual mistakes or suggest me better expression (WITHOUT ANY FEE), that will be so helpful. A Korean's poor English should not be a shame at all, we just need to improve it when we need it and want it. I think it is a good idea putting 'RR' for a request for review too. A good suggestion!
