You’ve always been able to put links to videos in a post. Now you can upload videos directly from the forum!
When you create a post, click on the new video button on the edit bar.
A small window will pop up. Find the file, give it a title and a description (you don’t have to but it’ll be helpful) and click the Upload to Vimeo button.
Your video will be uploaded and transcoded, and can be played directly from your post.
Videos are uploaded to the forum Vimeo account. You don’t need to have an account there yourself.
Content should follow the usual forum rules and may be removed if unsuitable.
