You can bring the post back to life by posting a response, or you can start a new topic and have a web link the old thread, or quote the old post in your new post in order to ask your questions. Consider if its really worth bringing an old topic back to life again by the quality of your post. I would go for posting a new thread and linking the old thread.
I have not checked out ES Wiki and I never checked out ES Facebook either but thats also because I dont have an account.
