Hi,I have downloaded the K2 plugin for Xmap and configured it, but no K2 item is showing up in the sitemap. 
Anyone has done this before? Should I take another step to include K2 items in the sitemap?

yes, through the xmap component you can install a plugin for K2 support. You can find the plugin here;

extensions.joomla.org/extensions/extension-specific/xmap-extensions/10297

Make sure you enable the plugin too, and take a good look at the configuration - if set to show every article loading times can get very high on a big site.

Thanks, solved. I had to click on that red circle with a cross in it to enable it! Guess one of those developers common sense...

bit of a late reply, but you need to install  the xmap component under XMAP, not under the regular plugin installations.
