I've spoken before about how amazing Nanowrimo is as a writing community, and as an activity. It is brilliant, and I love it everso much - for those who are unfamiliar with the concept, it's writing 50,000 words in the month of November: http://nanowrimo.org/
If you like writing, I cannot recommend it a lot. I've got a lot out of the community, everyone is super friendly - you get to meet fellow writers online and there are meet ups. And at the end of the month you've hit 50,000 words, and even though they may not be high quality - that's the entire point of it! It gives you a chance to mess around and do fun things, to experiment, and if it doesn't work out, then it doesn't work out but you've at least had the practice!
Well, that's in November. But for in the summer, there is CampNanowrimo which works similarly - but you set your own word count goal, and you are in a cabin - a group of people who can be random, share your interests (age, genre, word count), or you can make a private cabin with your friends. So you get to talk to people, get to work on your own goals (CampNanowrimo is set up for you to be able to work on editing, scripts, graphic novels, research, crafts or whatever you would like - whereas Nano itself is looking at fiction) and then there are a lot of very helpful writing resources.
And then *drumroll* there are the forums:
Here you can find cabin mates, talk, and give feedback (and there is still access to the main forums which has a wider range of forums).
Here are my top 5 forum threads from Camp Nano 2016 - if you're looking later on, they may be gone, but you will find other fantastic threads instead.
5 Favourite Line(s)/Scene(s) so far: Here people can share their favourite work so far, and get support and compliments!
4 Unfortunate Google Searches!: People sharing those searches that they've made, which are...awkward to say the least. If you've been writing any kind of topic, you know what this means - murder methods seem to be a particularly common issue.
3 Say Something Kind About The Excerpt Above You: I just love the concept here - everyone supporting each other and being really kind, encouraging each other. Writing is hard and can be lonely, so community is fantastic
2 Camp Dares: Stuck on your writing? Take a look here for suggestions of what to write
1 Nanoisms: The excellent typos that happen as people write. These are hilarious. Definitely my favourite part of Nanowrimo as a whole
Go poke around the forums, and feel free to link to anything interesting you find!
