Hope you all are doing great!
For authors finishing up their fics but need a little extra help there are some comms around livejournal that are great for motivation.
First off,
ficfinishing has sign ups open and Supernatural is one of its accepted fandoms. You sign up with your story for the month (sign ups end on the 11th!) and each day have the chance to share your current word count, have access to writing guides, and have the opportunity to find a first reader (basically a cheerleader you can send your fic to and get feedback and encouragement from).
Secondly, there is
gsd_rtfn, a great community that runs in week long rounds of intensive writing. You are able to share snippets of your fics with other writers and if your interested in taking part in this round
sign ups are here.
Also, remember there is always
sncrosssupport. If you need that extra nudge, are looking for some feedback on a part of your fic or plotline, or are in need of a beta just make a post there and we'll see what we can do to help you (if you are an author and aren't a member already go ahead and join, membership is moderated and you will be accepted ASAP).
Good luck to everyone and in the next week there will be a post up on how to turn in your final draft. Remember, those are due May 23rd (two weeks away!).
