I'm used to Wikipedia's Wiki, and now that I'm using TWiki at work I really miss the ability to discuss a page outside the page but still on TWiki.
Have I missed a button or link somewhere? Is this possible?
In MediaWiki (Wikipedia and the like), every page has a discussion page associated with it. This is not the case in TWiki, at least not by default. The administrator can built something similar, but as a user, all you can do is manually create and link discussion topics.
