Mine are some of the communities I have created:

!artbykids@lemmy.world - Community to share artwork created by kids. Anything creative is considered an artwork.

!alternateuniverse@lemmy.world - Improv community where anything and everything can happen. It’s all true. Continue the conversation.

!in100words@lemmy.world - Answer any question/prompt in exactly 100 words. Your answer can be a rant, story, poem, essay, advice, instructions, anything, as long as it is exactly 100 words.

What are your favorite communities needing some activity? May be we can all find some new favorite communities to grow.
