I wanted to know if anybody has been working on an extension to lock discussions after a given time of inactivity ?
For the features part of it, it could be nice to set per-tag timeout, so it can be made short for a "help" tag and longer or disabled for general topics.
I might give it a try if nobody is on it. Making it work like the read-all feature should not be too hard (that is, do the calculation based on last activity per-discussion in the guard logic instead of locking topics for real, which would require some sort of cron job)
