I've never understood this: I get several emails every week where someone asks me to send them a link to one of my videos or a playlist.
There is a Search button right on the channel home page. If you're asking for a link to a certain video, then you already know it exists, right? Even if you weren't aware of the Search button on the home page, wouldn't you just search from YouTube, Google, Bing, Duck Duck Go, or whatever search engine you use?
The playlists are available from the home page as well. And of course you can use "playlist" in the search field in YouTube.
It seems like it's more effort to email me asking for a link rather than searching for it on your own. Especially since I don't respond to requests for links.
