Thank you for your query, Pāvils Jurjāns: it usefully raises the issue on the public forum.
Please create a support ticket about this. It will go to Amara's tech staff who can help you.
I think you should contact Amara customer support and tell them the problem you are having and then ask them to help solve it.
Thank you, Tom: that's what I was advising Pāvils to do
I used to log in to Amara.org, but using my TED.com account pass. Now that TED.com doesn't use Amara.org platform for subtitle translations anymore, there's no more option to log in by using the TED.com pass.
I had some valuable history and memberships/permissions in that Amara.org account, I would really like to regain access to it instead creating a new account. Is there a procedure to follow through, for migrating the account I used to access by using TED.com pass, to a basic user+password access?
