I am Carlos (machimon.wordpress.com). I’m trying to embed a youtube video. I see there are two ways:
1. video embedder (1.7.1). I downloaded it, created folder in C:/wp-content/plugins/video-embedder but can’t find WordPress Plugin page to activate it.
1 does not work for WordPress.COM blogs. It only works fro WordPress.ORG blogs.
Here are the instructions for putting a YouTube into a WP.com blog. Note that WP.COM has security restrictions which mean some code is stripped out here. Consult the Support documents if you have trouble; often, there is a shortcode.
