My user posted message day ago. But I don't see him in the users list.
Please, tell me why?
Building posters ranking is expensive on larger forums. For this reason Misago relies on periodically fired cron task instead to prebuild this list once in a while:
Misago comes with example cron file that one has to customize to work with his or her setup, but is unlikely to work out of the box. You may have to specify path to your virtualenv python as well Misago manage.py.
