I recently evaluated the hosted version of Confluence and was very impressed, especially with its ability to embed a web page. I recommended the software to our company and we are evaluating the locally-installed version now, but I can't embed a web page. It seems like there are other features I am missing from the hosted version, and I want to give Confluence a fair Proof of Concept trial: what plug-ins would I need to buy in addition to the base license to match the hosted version of Confluence?
