I understand that sometimes when a particular thread is deemed to be irrelevant that the Mods "sink" it so that even when a new comment is posted, that thread is then not bumped back up. However, I have just tried to resurrect a thread that I think is interesting (as I've been told that if I want to read interesting discussions, I have to be pro-active about this) but it hasn't been bumped.
Has this been deliberately sunk? In future, could the Mods/Admin maybe indicate somewhere when they have sunk a thread and give their reasons for doing so, otherwise either I'm going to be wasting my time trying to bring back interesting (to me anyway) threads or wasting your time by duplicating threads that you believe should be discouraged.
Maybe in this case it is a bug, but either way, some info would be appreciated.
