dunkel, i for one would enjoy seeing your video. you can't upload them direct from your pc or smart phone, you have to upload them to you tube. (easy, but you have to have an account). when you upload the video to you tube you will be given a code or just click on the 'share' button, copy the code and insert it in the body of your post. in composing mode you will only see the code, but if you 'preview' your post you will see your video. any problems or questions, just holler at one of us admins and mods, that's what we are here for! looking forward to seeing your video, hope you and yours are doing alright?
the code would look something like this:
