Yahoo Groups got an upgrade yesterday. Now not only can you quote videos from other sites, but you can also upload local videos to Yahoo Groups. The maximum size for a single uploaded file is 50M and most common file formats are supported, such as: .wmv .rm .mpeg .mov .flv etc. You can set the cover of the uploaded video freely, provide link URLs and embed codes so that you can repost the video to other blogs or web pages.
