There are lots of ways of sending videos of yourself to the forum. The easiest way I can think of is by using your smart phone:
1. Use the phone's front-facing camera to record a video of yourself.
2. Share the video to a cloud-service provider of your choice. YouTube, Google Photos, Apple Photos, Dropbox... anything works, really.
2a. If uploading to YouTube, mark the video as "Unlisted" - that way only people you share the link with can view the video.
3. Once you upload your video to one of those providers, copy the link.
4. Paste the link to this forum.
I'm happy to help with any of the steps above, and I'm sure others may have more input.
Looking forward to seeing you play
