Didn't read this thread but I have been on forums since 2001. To search within a forum, simply go to google.... Search (example given), "which intake should I buy? Site:nasioc.com" (or insert whichever site you want to isolate the search to) . You can also click advanced search option in google (will do the same thing ), but simply adding site:website.com after the search keywords it will only pull from the website you choose.
I literally never have to post unless I feel I have useful info to contribute , 99 percent of the info you need is somewhere out there. Just have to know where to look
