Help me to understand a bit better (I'm more used to operating and posting to Youtube and Reddit). By "making the thread", do you mean making a post? Like, I'll create a post with a simple title and simply intorduce/provide the link for my playlist?
If that's the case, do you want me to make the post also for the Roach video playlist? Also, I didn't know Roach = Andrew Roth. I watched parts of those rebuild videos and it's incredible! Truly remarkable mechanical skills he has!
Yes, you have it, in this forum the button does say "create new post", other forums call it a "thread" with the collection of posts inside. It's an internet thing.
But yes, just start a new post with the title of your choice and put the description in the post, then include the link to your YouTube home page so people can go and reference the video they need.
It would be fine to include Roach's with yours, or fine for you or anyone else to start a new thread with his home page listed. Once upon a time, a couple of people have complained about the high number of pinned threads in certain sections, but as long as they're useful to the forum I don't think it's a huge problem.
Sometimes I'm concerned about using his name in a post, versus using his screen name, but unless I go fetch the link every time there's no other way to tell them how to find him at YouTube.
Videos like that are helpful for anyone doing a job for the first time, or maybe forgot how something goes back together. Just have to find the relevant video, I think they're all listed as Part 1, Part 2, etc., without descriptive titles. But they're definitely handy.
