If you like to write drabbles, have you checked out slashthedrabble and slashtheimage? These multifandom communities post challenges every week or so. The first community's current prompt is "First Time" and slashtheimage's prompt is a photo from Boothbay Harbor Maine, which was suggested by (what a surprise!) me. I'd really like to see more people writing drabbles for these communities - please come check them out.
