Unconventional Courtship is a fun little challenge. (From their page) - is a panfandom fic fest where you write and post a 1000w+ fic based on a M&B/Harlequin plot. Fics will be posted to this community, staggered through August and September 2017, from 18th August.
There are tons of prompts and the rules are few and easy to live with. It is the perfect way to shake off the summer blahs and get the little grey cells firing. If nothing else, take some time and read the various prompts. I bet you can find something that strikes your fancy. I've already chosen mine. :D
