Can I run a thread and remove it in a few weeks?

Geez cunning. Although I don't have any of the footage saved anywhere so kind of like that some memories still exist through the form of old you tube vids. I wonder if I can change the link at yt, so that it fails.

Don't rely on youtube for saving things - download it as well so you always control it. Nothing stops hosts from deleting old content or using it as they please by changing their terms of use.

You can also leave them on YouTube forever and just switch their status to private so no one can see them, other than you.

Flyblown has it - once signed in on youtube you'll go to the left side "Your Videos" button, then under the column "Visibility" select the dropdown tab for each video, and click "Private". You won't be able to share the link to anyone or view it without being signed in. Unlisted just means that it's not searchable, but you can still share the link with people.

Personally I would prefer to be able to delete or edit content... it's a good feature on forums so you can add information, correct it etc. Works well elsewhere.
