Hi! Very possible you've already signed up because of these helpful responses from other people, but yes, you absolutely qualify if you plan to participate in Yuletide this year. (And sometimes even if you don't! But in your case that's not relevant. :)) Some years I will check who is and isn't signed up, but I probably won't even do that this year as we've opened sign-ups so early.

But yeah, what's most important is being able to communicate + go to the post office (or send a book in whatever way makes sense for you). Welcome!
