For questions how to actually use the app, like how moderation is done, you have to look for help in the upstream app community.
Overall for commento, the Cloudron package still depends on https://gitlab.com/commento/commento/merge_requests/88 which is stagnating for a long time now. If you like chime in there to raise some attention, so we can eventually proceed to follow upstream releases better.
@girish it would be great if this behavior was described in the cloudron package documentation. it's good that i have now fixed all my email problems in cloudron, but it would have been even better if i had known that the ü in my last name was causing the problems i wanted to work around 😉
