Might as well assume it is. It's hard to say it was ever really here anyway.
I must say that I can't believe they haven't stickied a post "how to search this forum with Google" yet... Well I tried. You can search the site if you go to google.com, type in what you want to search and add "site:www.supraforums.com" to either the beginning or end. It's not as precise but it works.
