Ok. I've managed to add an automatic poll to the new topics of my Code Exchange Forum.
By default, each new topic has a poll whith the following question and answers:
Q:What is your opinion about this topic?
- Very usefull
- Usefull
- Limited interest
- Useless
This is transparent to user who does not see the poll when he creates its new topic. The poll only appears to everybody when it has been posted, and users can then vote.
I have also modified the code so that the admin can modify the poll Q&A if he wants or just add some more possible answers.
I will write something about it as soon as I get time.
