XF 1.5 How can I set a time limit for post edits?

[rhodes]

I would like to extend the time users can edit their posts. But unfortunately I cannot find a setting in the ACP. Any ideas?

Can I also extend this setting for a single forum?

It's a user group permission, "Time limit on editing/deleting own posts (minutes)"

Thank you @Martok
