Welcome, stranger!
We will upgrade our [official sandbox|http:// sandbox.onconfluence.com/dashboard.action] to Confluence 3.2 soon, but if you want to try out the new features now already, just leave a comment below (this server runs the Beta 2 release already). Use the RTE and type "*\!*" or "*\[*" to activate this cool feature. Or check the [DOC:Confluence 3.2 Beta Release Notes] for more in-depth information on how to use Autocomplete and the new Links dialog. Wiki Markup
Oh, and the nice styling you see here is actually part of Confluence 3.2 too.
