Auto Close & Prefix

[Wurstteppich]

Hi,

we have some kind of support forum and would like to auto-close and prefix threads after x days between now and the last change was done on a thread.

Does anyone know a mod, combination of mods or other method to accomplish this and would like to share it with me?

Anyone?

If someone has worked out a workaround by changing something in the templates or even knows a theoretically but never tried solution it would be very welcome.
