Hi there,
Sorry for getting to this so very late.

So right now, we use an already baked in version of a redis task queue manager as implemented in flask_rq. You can find its instantiation here:

Essentially, the queue is only really used in a couple of places. One is in admin/views and the other is in accounts/views. Both times it is just used for emailing. So if you want to use celery instead, just go ahead and rip out any reference to flask_rq in those files and replace it with your own celery integration.

The main calls to replace in the application are get_queue() calls. Does that help?
