Sounds good to me, I'll just add a couple of things: Don't post poetry just for the sake of it! And also, please, PLEASE Beta your work or ask someone else to before you post it up. Typos happen, but having them all the way through makes things like poetry incredibly hard to read.
Hold on, when you say post poems in one toipc - does that mean one topic per user? Because I can see how that'd make good sense.
