The pool is still open courtesy of ng_moonmoth if you wish to join in. Look on the sale page and you'll see which poems the pool will be covering. In several cases, the pool has sponsored prerequisites, which clears the way for the sequels "Celebrate and Cherish" and "The Supreme Quality for Leadership."
For those with a short budget, note that all the sub-epics are still available, as are the epics under $20.
If you're planning to participate in the Holiday Poetry Sale, now is a good time. It ends tomorrow evening.
