Well… It seems I'm not the only one to be suffering from this appalling draconian system Google have put in without any thought.
I had a google account with my business email to use with analytics etc.
I set up a gtalk to communicate with someone who does not have (or cannot install) Skype.
This requires a gmail account
ALL OF MY GOOGLE AND YOUTUBE SERVICES ARE NOW LINKED TO THIS REDUNDANT ACCOUNT BY DEFAULT!!!!
You cannot delink it as the primary email as it will delete all your data (according to the google account help pages)
You CAN apparently delink/relink your 'other' account with Youtube.
I attempted this today, but two things:
1) The type in field for the Captcha code is INVISIBLE (white on white - it's right below the text - the the left of the captcha, not even in line with it!)
2) An error appears saying 'Cannot link known user account' - or something similar.
Also… This forum will reply to my unused googlemail account now and not my normal business email - doh!!! It appears you cannot change this. because of the first point I mentioned, currently, deleting the google mail address will delete the whole account.
Please fix this mess Google / Youtube. I want my videos back and be able to actually use my Youtube account which I presently cannot.
