most times the topic would be merged and consalidated,,if a particular topic has intrest or at a juncture where users opions are wanted or needed ,,ie effects put in updates,,then a poll posting will be generated,,
if you want a poll topic then i not shure who to ask to get it set up,,but the fourm users input on suggestions ie +1/+100000000000000.usaly gives the same effect
dont worry about not seeing familiar topics,,some times its hard ,,especialy when the heading or topic meanders off topic
