I have taken over as an administrator for a support forum that has been going since 2012, and now they have change the system to bbForum which is nice. Since the forum has been up since 2012 there are loads of old topics, and that leads me to two questions that in a way are related to each other:

1. Is there an easy way, either built in or with an addon, that can batch close old topics?

2. Is there a way, again either built in or with an addon, to automatically close topics where nothing has happened in a certain amount of days?

Thank you for your time and help.
