creating new activity stream types
 

So I have lately managed to create a custom ajax vBulletin activity sidebar with a php switch statement that accounts for the different activitystream types.

Now I would like to create a status/commenting system that I can add to the activity stream that will allow users to comment on the activity as well as share pictures etc on their timeline.
in order to dynamically insert data into the "activitystream" table, I need to create more activity stream types with there respective packageid's.
Would I need to create a new package in table "package" ?

Or just use one of the default ones?
