Would it be possible to create an account on a dedicated server with unlimited resources? I've noticed that when you go to create an account through WHM it has the option of selecting a package or assigning whatever resources. Under some fields like bandwidth, ftp/email accounts, etc. it automatically puts in "unlimited" in the field. Is it possible to actually do that? I know that you can't go above what your dedicated plan allows, but could you make an account that's flexible instead of a set package?
