Now my question to you, is it the responsibility of the original author to correct the information in an old post if it has changed, or should those who read the information later verify it themselves? Have you ever come across any old information that was once correct but is no longer valid?
I cannot give you a statistics of how many topics are created in this forum on a daily bases but one thing i know is that there are enough updated post on the informations you need.
Now to answer your question, the information in that old post will not be corrected in that particular posts, rather new posts will be made regarding the new development, some can be very detailed to the point where it takes you back to how it used to be, how it is now, and the mechanism behind it. So looking past recent posts and settling for topics created 3yrs ago and more may feed you an outdated information. Unless for topics that are pinned.
While we have soo much information on this forum, you still have to make your findings to ensure correspondence. And in cases where there are contradictions and the topic isn’t old, you can aswell share your findings in the forum.
