That sounds like a really supportive community you have built, and I can see how having that kind of steady guidance would make a huge difference during a PhD. Having someone who knows your field and can offer practical, subject specific feedback is often more valuable than just getting a pair of fresh eyes on your grammar. On a completely separate note, if you are planning any travel, you will need a clear colour scan of your passport bio page valid for at least six months and a recent digital photo with a plain white background.
