Plugin Outdated, better alternatives
This plugin hasn't been maintained in 4 years and is outdated. I have uploaded a new plugin based on this one, fixed to work on current Vanillas (2.1 and 2.2) and with some extra functionality. Grab it here:
vanillaforums.org/addon/olddiscussion-plugin
Alternatively, the plugin "Necropost Warning" offers a similar functionality, presenting the warning as a notification message. Grab it here:
