This year I've decided to just respond to the days which seem relevant to me.
Day 4 - Comment to someone you haven't ever interacted with before or introduce yourself to someone you've interacted with and friend/follow them.
I commented on a few posts on Day 3, which were recs of particular parts of canon. In particular someone posted about
Alias Smith & Jones, which brought back a lot of memories from my teenage years.
Day 5 - In your own space, promote three communities, challenges, blogs, pages, Twitters, Tumblrs or platforms and explain why you love them.
Firstly, as a Sherlock Holmes fan, I'd recommend
watsons_woes for all forms of Dr Watson and
holmes_minor for ficlets of 500 words or less for the original Arthur Conan Doyle Holmes. Different activities and very friendly participants.
Secondly,
fan_flashworks for all types of fanwork, written, drawn, edible etc. Challenge prompts every 10 days and there are badges to be earned. (I like earning badges as can be seen from my profile). In addition, there are bingo cards to celebrate 7 years of the comm.
Thirdly, as a keen drabble writer (exactly 100 words) I would recommend
drabble_zone and
100words Multi-fandom and great for trying out a new fandom, or simply writing something for a book/play/film/tv programme you may not write about again. Prompts every week.
And lastly,
fandomcalendar is a great source of both multi-fandom and specific fandom exchanges and challenges.
