Update WikiPathways videos on Youtube for new website

[khanspers]

We have a playlist here: https://www.youtube.com/playlist?list=PLLxzpENhQBVj4os5dD29awfzbO5Ju1Ox8

Videos that need to be updated for the new website:
WikiPathways Navigation Tour -> Remove/don't update. Replaced by TogoTV video tour.
WikiPathways Introduction to Editing -> Mostly obsolete. Should be replaced by a PathVisio-focused video showing the basics of creating and submitting a new pathway
WikiPathways: Create a pathway, part 1 -> Obsolete in terms of WikiPathways. Content is mostly drawing in PathVisio, which should be covered in PathVisio-focused video.
WikiPathways: Create a pathway, part 2 -> More PathVisio drawing content. WP content is no longer relevant.
WikiPathways: Create a pathway, part 3 -> Remove/don't update. Content is not relevant for new site.

What content should videos cover? Ideas:

• Communities: Add a pathway to a community, create/update community page
• PathVisio: All aspects of pathway drawing, uploading to WP, editing existing pathway. This should include tips and tricks that are not described, like how to find empty nodes (search for Gene Product) and other similar things.
• Add citation to pathway under "Cited In"
• Update user page

Shorter task-oriented videos can be linked to from FAQs, for example wikipathways/wikipathways-faq#19. All can be linked to from Help.

Also, about the old outdated YouTube videos: Should we delete them? I assume so.

Re: existing outdated videos on YoutTube
It seems I can't recover the credentials for the account I used to upload the outdated videos. I suggest removing them (and others that are outdated) from the following playlist instead:

As for potential new videos, we can discuss what's the most useful and make a plan.
