- Submitted an article and after two weeks received a generic rejection email without explanation. After asking for feedback, even very brief feedback, I received another, different standard email explaining that they cannot give feedback given the number of submissions and their aim to get back within the three month timeframe. Would recommend to only submit articles of which you are certain you will receive some form of genuine feedback, because otherwise the 'review' process is useless.
