Shortcode needs to return not echo

Hey guys,

I’d really like to use your plugin for managing my board’s meetings, but your shortcode is adding content to the page using echo and not return, making it appear at the top of the content area no matter where it’s placed in the page.

You can test this by adding content above the shortcode, and then looking at the page. The list of meetings and adjendas will show above that content, not below it.
