No problem, (I alluded to this yesterday). Just run a web server on the linux machine and have it issue HTTP redirects from domain.com to www.domain.com. You could also port-forward, but I think the redirect is easier to get right (and less disruptive as you are getting it right). Apache would do just fine. The bigger picture: Maybe you want to bring in an experienced firefighter for while, learn from him and then take over? Good bosses usually like 'this is new, I'll need to learn' almost as much as they like 'sure, I can do it.' Yours in particular should by now. BM
