The account management servers were down yesterday for maintenance, so that might have been the problem.
Hope thats it, but i did try and create an account several weeks ago and gave up.
Just tried it from work and I can't do it here either. That's 2 PCs and an Ipad, three usernames, four passwords and no errors, just a simple refresh of the form on submitting.
Starting to think I need to find a third party to create me an account so I have sent an email to Turbine; not hopeful...
