I wanted to “embed” this video, which is in Vimeo, using "embed code" in a moodle.org post, but moodle.org forums do not seem to support this. While creating my post in HTML mode, I insert the embed code and it shows correctly (while editing), but when I finally post my message, this embed code is automatically removed.
This embed code comes directly from Vimeo, my video server platform. It works fine in my own Moodle, so I assume that either moodle.org forgot to turn the Vimeo player on, there could be some moodle.org security issues that prevent iframe embed code, or something else is going on.
Here is the code that I was trying to embed.
