*blinks* There have been atleast 8 poetry prompts by Romulus, links in the Lists article. However, I understand Rom's been busy IRL so we haven't had a new one in a while (~ a month). If you want to fill in the void of prompts (and would be willing to offer meaningful themes and feedback - see Rom's threads), I see no reason why you can't start a new one.
E: I knew that article would come in handy, two opportunities to cite it in one day :D
