We need a necro colour-code for threads which have been inactive for X months (to be determined by forum rules) and a variation on the necro-colour for threads which have become active subsequent to a period of inactivity spanning X months or more. 2017.1227.1015: Just to clarify, I tend to think that rebooting an old thread is better than duplicating it with a new one - but as long as necro-posting is frowned upon, we might as well have tools that make it easier to avoid doing.
