We're about to launch a new branch (well its always been there but we're doing it up) off our software website (micromail.com) to deal with student software. We've purchased the domain studentsoftware.ie, but im wondering should we hold the software section of our site on the new domain, or should we just use studentsoftware.ie as a redirect to a student section of our own site, say micromail.com/students? I would tend to think the latter would be better as it would rank higher and be a lot easier than starting from scratch, but branding wise, would it be pointless telling people to visit stuentsoftware.ie if it just redirects them elsewhere? Any advice?
