Looking to use thread title, inside post.

[Win Z]

Hey there,

I'm hoping you guys can help me. I'm basically looking to do a couple of things;

A) I'm looking to display a message, inside threads (preferably in the post, but anywhere inside the actually page is fine), that are in certain forums, and displayed to Guests only. How would I do this?

B) Inside that box, I would like to display the thread title automatically. EG:

1. Thread titled "Steve", the message would display: "Steve <standard text>"
2. Thread titled "Bob", the message would display "Bob <standard text>"

How would I do both of these things? Please help.
If significant modification is required, I'm willing to pay -- although if you're gonna ask for an extortionate price, don't bother, I'm not stupid.

I'm using vBulletin 3.6, by the way.

Kind Regards,
Win Z
