I took part in The People's Friend writing hour today (it's on twitter every Tuesday morning 11-12). This is a good way to 'meet' fellow writers, and ask questions of the fiction team. In response to a question, about characters aged 70, they said that if characters had a story to tell, age wasn't relevant.
I asked about stories from a child's POV, as I've not seen many in the magazine and was told 'We really like junior viewpoint stories, but we don't seem to get a lot of them sent in!'
Talking of twitter writing events, you may like to join #WritingChat on Wednesday evenings. It's open to all writers and covers all genres. There's a different theme each week, plus you can ask questions and suggest future topics. To take part, just tweet 8-9 using the hashtag.
