where is the query that is called when someone insert a post?
because i want to add a value (user -> points) when someone insert a post..

thanks!

if you can, if you tell me also where is the query about a new registration

Look in includes/class_dm_threadpost.php They use a datamanager to insert the data.

what is a datamanager?

There are articles about the datamanager. I don't know how familiar you are with php, but go read up on object-oriented php.
