GRADBritain is an online magazine that's written for and by postgraduate researchers in the UK. They're always looking for new articles and will pay £50 for any they use. Some of the articles in it can be quite contentious, others have practical advice for researchers and some are just meant to make you laugh (and remember that the PhD isn't the only thing in your world). The next deadline is 1st Feb. If you think you have a unique or interesting perspective on the PhD or something you'd like to share with other researchers then why not have a go at writing an article?
