Also is it wrong for someone else to discuss what a person have talked about before?
if you want to share information, it is only natural that you search the forum first (use the search feature). whether the information you are about to share has been created by someone else on the forum or not.
although we usually encounter it, as much as possible to avoid it.
it would also be better if what you share is to complete the information. or an update of old information that must have undergone development. the discussion will be fresher than sharing information that already exists.
