I ask at least 3 stupid questions a week..just ask the other dev's :P
It's really hard to determine what's current and what's not in the forums.
The best course of action is to look for wiki pages concerning the topic you are interested in.
If, at that point, there's no resolution, you can search the forums. I definitely would not trust any information that's more than about three
months old..but, there's no definitive length of time since some things often change over-night and others haven't in ten years.
We try to insist that people search for solutions before posting new questions..but, tbh, there's no way to keep people from finding old information
without deleting a large amount of posts..and that's not likely gonna happen...
So, no question is stupid
