Hello MONKEY!
Yes, we do. Event modules are used for creating hooks. From the documentation:
event modules (from Q2A 1.4+) are notified when something important happens, such as content being posted or voted on. They can be used for analytics, notifications or integrating with external services such as Twitter. The Event Logger plugin included with Q2A logs all events to a database table and/or log files.
I hope this information is useful.
