What does AskBot use djcelery for?

I'm working my way through the code, and I'm still a little unclear on what askbot uses djcelery for. My understanding of celery is that it lets one run asynchronous jobs and djcelery integrates it with django. Does askbot use it to run potentially long tasks (like sending email) asynchronously after a post is updated to avoid UI delays?

That's exactly what askbot uses celery for - to send email asynchronously when the posts are made (instant email alerts). The docs need to be updated on how to configure celery.

Default configuration does not involve asynchronous tasks.
