Dear all, in response to the introductory video of yourselves, i would like to recommend that everybody open an account with youtube and upload your video to your own channel and make it private and invite only those you wish to share the video with if you prefer not to make it public. Here’s a sample of a 4.53 minutes introductory video. Yours need not be that long. 2-3 minutes is more than enough. Hope this post helps you with some idea.
