This 'quick' 9-Step was developed for a couple of friends who were attempting to create YouTube Channels for their organizations. The YouTube procedure to accomplish this is remarkably complicated and confusing due to a recent change that integrated YouTube with Google+.  Here's some background followed by the set of steps I recorded while performing this awkward maneuver.  I hope it helps.

   

The goal was to create a YouTube Channel for an organization that would be managed (video uploads) by multiple individuals.  This feature of YouTube has been available for some time, but changed considerably in late 2013 when Google began intertwining YouTube and Google+.  This 'integration' seems to have created somewhat of a rats-nest of Google accounts, YouTube channels, and Google+ pages and profiles.

• You'll need a Google account that will be used to anchor the Youtube Channel. For non-profits, it would be highly recommended that this account be managed by a permanent employee as opposed to a short-termer or volunteer.
• Your YouTube channel WILL have a Google+ page associated with it, READ THE TERMS OF SERVICE
• Get Personalized help from Google if you configure yourself into a corner!  (interesting find!)
• If you are helping others, consider working through the steps below then Transfer Ownership of the Channel 

1. Sign in to YouTube.  Use a gmail address associated with the company/organization.
   
   
   
   
2. Click on the gear (settings) icon in upper right, then highlight & click "Dashboard".  You will hopefully be prompted to create your channel.
   
   
   
   
3. Click "Create a Channel", but be careful when following the link to "Set up your channel on YouTube" screen (see right) ... click on the nondescript link "To use a business or other name click here" to create and properly name an organizational page. Google Help HERE [Yeesh!] 
   
   
   
   
4. The "Create a new channel" dialog will be used to name and classify your channel.
   
   I'd recommend using your organization name for the channel name since this will likely become your Google+ presence. Select "Company, Institution or Organization" category and appropriate  content rating (any age, 18+, 21+, etc). Now's your chance to accept the Google+ Pages Terms of Service before continuing.

5. That's it!BUT ... Using YouTube will never be the same!  More Google Help HERE
   
   
   
   
6. To add another manager to the channel you'll need to dig back into settings, first on YouTube, then on Google+.  Click the gear icon again, and highlight/click on "YouTube Settings" 
   
   
   
   
7. Follow the "Add or remove managers" link back to Google+.  Google Help HERE
   
   
   
   
   
   
   
   
   
   
8. FINALLY, click the "Add Manager" button in upper right of subsequent screen to send an email invitation to the unsuspecting colleague who will help manage the YouTube channel.  It would be advisable to warn him/her first because the email does not currently mention YouTube, simply an invite to manage a Google+ page!   Google Help HERE
   
   Note that you can only delegate to Google account holders (Gmail, Google Apps, Google+, etc).   They will also be assimilated into the Google+ world!  You may want to apologize for this when you pre-warn of the cryptic invite.
