I've noticed this happening quite a bit lately...members replying to poem threads and quoting the entire poem in the reply. STOP DOING THIS. It's a waste of space (If you reply to the thread, we all know you're commenting on the poem, there's no need to re-post the entire thing), and it's really, really annoying.
Also keep in mind that replies must have some substance. If you like a poem, you should be able to coherently explain why, beyond just saying "It's cool!!" A single sentence is fine, as long as it gives the author some idea of why you liked/disliked it. Constructive criticism creates better writers; inane pandering does absolutely nothing.
