This is slightly difficult because I can't be sure whether the tools that I can see are available to regular members
I have a "Thread Tools" pull down menu along side the "Search this Thread" "Rate this thread" bar. In there there is an option to add a poll, along with options to email the thread and view a printable version.
I hope you don't mind me testing out the command, I hadn't used it before. I have inserted a poll asking if £110 is too expensive, yes or no. I have made it public so that, in theory, you will be able to see who voted which way, which might be handy when you work out your buyers lists.
If you want anything changing, or if that option doesn't exist for you, please let me know.
