When working in the Forums tool, it is strongly recommended that you use the site navigation, NOT the back and forward buttons in your web browser.

Additionally, you should compose messages or grade using only ONE browser window or tab.  Making changes in one tab or window, such as writing a post, and then moving to a different tab or window that was open before you made those changes may cause you to lose the content you were attempting to submit and/or encounter an error.

You can embed a video file in a text box using the Rich-Text Editor. Video and audio file types that can be embedded in the editor are .MP3, .FLV, .F4V, .MP4, .3GPP, .M4V or .MOV files.

For information on making video files accessible, see How can I make videos and audio files more accessible?

Tip: If you are adding content in the Lessons tool, you may also insert videos directly as individual items on the page, rather than within the Rich-Text Editor. See the articles on Lessons for more information on embedding and linking items on a lesson page.
