I dunno.
I guess the idea about necro being bad is that you bring up a dead topic which drowns out current stuff. but if current stuff is moving so fast that virtually everything is drown out in five minuets anyway… who cares? I dunno, I am not a moderator, lol. If i accidentally necro a thread I don’t worry about it much.
If i find an unanswered thread and it was first hit on google I think it’s good to add an answer if i have one. just to help out other searchers.
