Are there single page forum engines?

Question

CMS

Authorization through social networks is desirable.
No sections are needed. It is necessary that the topics just go in a row in one list.
Well, and fashionable flat design, I would like =)
Thank you!

You can create a project on the hosting of open source projects - for example, on codeplex.com. Comes with wiki, forum, bugtracker, git.
For discussions, you can also use the page on the social network, oddly enough, or google groups.
