Hi,
We have a special Kunena plugin which add some moderation feature.
It offers us a special listing with open thread and we can close it manually when the problem is solved.
Each time a user (and not a moderator) reply to a topic, if the thread is re-open.
With it, we can't forget to answer to a question
Regards,

By the way, do not send me private message, use the "contact us" form instead.
