WASHINGTON (CNN) - Imagine that you get to design your own presidential debate, choosing which candidates you listen to and picking only the topics you want to hear. Yahoo!, The Huffington Post and Slate are teaming up to host an online-only, interactive presidential "mash-up" starting on Thursday.

Say you want to hear Bill Richardson, Mike Gravel and Hillary Clinton talk about health care. Or John Edwards and Dennis Kucinich discuss the war in Iraq. All you have to do is click on the candidates' pictures and the topic and press play.

"With presidential candidates announcing online and with campaign ads and fundraising increasingly online, presidential campaigns are moving to the Internet at breakneck speed. Online debates are the inevitable next step," Huffington Post's Arianna Huffington said in a press release.

The forum will be hosted by PBS's Charlie Rose. It will be available live on the Yahoo! election Web site from Thursday morning through next week.
