Ok, go to ''new thread'' option at the top right corner of the screen.
When you click it you'll get a box in where to write your post, and if you scroll down a little, you will have a little box where ti says ''yes, post a pol' or something similar.
Tick this box, write your post and click submit thread.
If you have problems, let me know. If you make a mistake, try again, and I'll close the thread you made a mistake on.
