How should one bring an older, but appropriate Q & A thread up to date?
Specifically, I am referring to thisthis question. But, I would like to understand what position the community consensus is for updating older questions.
Several of the answers, in this question, do not accurately answer the OPs question. Some are now inaccurate. I would rather not go through each answer and comment that they are wrong or incomplete(I'd prefer not to make other users look uninformed). How should I proceed in an older thread to point new users to updated information and keep a perfectly valid question current?
Or, am I simply approaching this in the wrong manner? Is there a FAQ that I can refer to on this etiquette?
Many of the answers that I have found here in my short time on the site have been useful, but slightly out of date. How can I add to the answers and distill the solutions with newer knowledge without having someone searching behind me and have to wade through cruft?
I've looked through the related links and haven't found an adequate answer.
