Comment to someone you haven't ever interacted with before or introduce yourself to someone you've interacted with and friend/follow them.
In your own space, set some goals for the coming year. They can be fannish or not, public or private.
I pretty much already did this on my New Year's Resolutions post. F-locked, since there are personal goals as well.
In your own space, post a rec for fannish and/or creative resources and spaces.
crack_broom: Super awesome HP reccing community. Each month, people sign up to rec different pairings/categories, and then they post four recs throughout the month. It's an awesome resource for people wanting to get into new pairings and a great place to share the love for your favorite fanworks.
