 <h2> Call for Sessions</h2>
 
-<p>The Call for Sessions for LibrePlanet 2015 is open from <strong>Monday, September 15th, 2014</strong> to <strong><strike>Sunday, November 2nd</strike> Sunday, November 9th, 2014 at 19:59 EST (23:59 UTC)</strong>.</p>
+<p>The Call for Sessions for LibrePlanet 2015 is open from <strong>Monday, September 15th, 2014</strong> to <strong><s>Sunday, November 2nd</s> Sunday, November 9th, 2014 at 19:59 EST (23:59 UTC)</strong>.</p>
 <p>This year, the theme of LibrePlanet is "Free Software Everywhere." We're looking for talks that touch on the many places and ways that free software is used around the world, as well as ways to make free software ubiquitous. Think "where" in the broadest sense of the word--it's not just geography-based talks we're after. What are some contexts where free software is thriving, and some others where it needs a push? How have you worked to gain a foothold for free software in your company or community? And what about free software on all of the myriad pieces of hardware we use, including laptops, phones, tablets, and even coffee makers? At LibrePlanet 2015, we're taking software freedom around the world, to outer space, and through all kinds of industries, governments, organizations, fields of study, and communities.</p>
