All right, let’s try different question – I want to add additional informations to topicmeta when posting new topic – how can I achieve this? 
Or at least point me to a plugin that is doing something like this so I could learn there…
add_action('topicmeta','hello_world');
function hello_world() {echo "<li>hello world</li>";}
I am also facing the same problem…
