NaNoWriMo (National Novel Writing Month)is shutting down after more than 20 years of hosting its annual challenge for writers. In a video and an email sent to community members, the nonprofit organization explains that it can no longer continue “after years of financial struggles.”

As shown in the video, NaNoWriMo interim executive director Kilby Blades details how participation and fundraising in the program have decreased in recent years. The NaNoWriMo site will remain online for “as long as possible,” though it will no longer formally host its writing challenges.

“We recognize that the closure of NaNoWriMo represents a huge loss to the writing community, and that grief over this outcome will be exacerbated by the challenges of the past sixteen months,” NaNoWriMo’s email to the community says. “This is not the ending that anybody wanted or planned. And—believe us—if we could hit the delete button and rewrite this last chapter, we would. But we do have hope for the epilogue.”
