If you find the wiki to be valuable, and want to integrate it into your own website, you can! You can create a page on your website (say with a tab called "wiki" in the website's menu) and integrate the whole content of the wiki into that page.
This is not merely a link, the wiki will be integrated into the look and feel of your website, as if it was your wiki. When people click around different articles in the wiki, they will stay on your website. This can be a great way for you to share valuable content with you contacts, clients, friends...
How does it work? Basically, you just create a space in a page where the wiki will load. The content of the wiki is not actually transferred to your server (so no extra storage or bandwidth for you). It also means that there is one single database behind this all. If a visitor from your website (or one anyone else's website) decides she wants to add an interesting information or correct a typo, this gets reflected everywhere, on all pages that integrate the wiki.
Additionally, certain keywords can be substituted on your own page to conform more closely with the language you prefer to use, for instance about the stages of organizational development.
In practice, you embed the wiki with a simple bit of HTML code (called "iframe"). Most popular web-design sites (e.g. wordpress, weebly, squarespace) allow blocks of HTML to be added on a page. Your webmaster should be able to do this in less than 5 minutes.
