More Letters?

For those of us who have been... is awe-struck the right word?... by Sarah Boone's letters, I need to know if there are more coming!

I'm certain she will be furiously writing away for ever, but will the letters ever see the light of day?

I'm actually asking from a legal perspective: I know that prisons have to vet incoming mail for contraband, but do they vet outgoing mail? Is she even *allowed* to write more letters (to e.g. the Court, the Judge - even content creators?) Or would it be against her rights to *stop* her writing letters?

(I wish I could wean myself off this case, but sadly, I seem to still be here in this fab sub!)
