We have new people coming to the game, the universal forum mantra says read the old posts before posting. So they do and if they post a new post talking about something old but RELEVANT to them there and now, someone in a nano-second is posting a link to the old post, but if someone comments on an old post they are necroing. It's high horse snobbery. We were all noobs at some point in the game and in this forum.
Now if it is just a "bump" then they are dicks . . . that is necroing and calling that out isn't snobbery. It could be Snarky, but then again, Necro and vampires kind of go shriveled hand in shriveled hand.
