Help with some small problems

[Hollister]

Ok i am fairly new to vbulletin and i was wondering how you would perform these small modifications,if they are at all possible.

1. If a topic has a poll, is it possible to show the result in the topic title?

2. Can you force someone replying to a thread to vote in the poll when they reply

3. I know a custom thread fields is available is it possible to only make this available on certain sub forums and preferably with a pre loaded drop down list.
