Post them in this club,
link, или possibly in both. Your Поэзия is both creative and writing, so it is appropriate to both clubs.
Now, as to where to post them in the club: if the poem is 25 lines или less, I'd post it in a Форум thread. For an article, I'd encourage Ты to post longer pieces and/or post several poems together (with a separate Название for each in the Статья - Ты could also set them apart with Обои if Ты wished). Places inappropriate to post your Поэзия if Ты want any chance of positive feedback: quiz, picks, answers. Видео are fine if Ты can make a narrative flow while still Показ your poem, with a beginning, middle and end. A good way to do this is to read the poem on video, either to the camera или over a slideshow. Обои can work with very short pieces, but I personally would avoid it. Users tend not to linger on Обои for very long - certainly not long enough to read verse.
