If you can't make a business case for the website to management,
why would IT build it for you? (And if IT did build it, then someone else would complain that IT is wasting resources on unauthorized projects.)
Pasting rich text from applications like Word into text or HTML environments is symptomatic of the more dangerous sorts of incorrect actions for which a good IT department must always be alert. Some things may make you job easier in the short term, but allowing users whatever they think they need at the moment without reserve is exactly the sort of thing that leads to security failures that can damage or destroy a company. I imagine that not having a job probably outweighs not having some extra website that ten people might use.
