Greetings, Fionn! I haven't been active in these forums for long, only since December 2015 (I signed up in 2014, but never got to it till later because of medical interruptions).
I think you'll really like it here. We trade feedback with each other and everyone benefits. It's great to hear what others write and provide your opinions for their benefit, and really nice to hear what they have to say about your own work.
And check out the competitions. They're fun! I think anyone can vote, even if you don't have entries.
Vicki
