Post news while making a newthread in vbulletin

[Inferno Dragon]

I have a very simple news system, with mysql fields (title, description, submitter, image) I need a hint, idea, help about doing this:

What I want is when someone start a newthread, the same entry gets saved in my news database as well..

can anyone guide me towards the right direction? I tried looking into functions_newpost.php of vbulletin but didn't get it that much..I thought of simple entering a insert query with the vbulletin "insert new thread" hook/query

Any help will be appreciated
