Thank you for the reply.
Yes, I registered "alangurling" only for an Akismet key as I was using the key for a WordPress.org installation. Unfortunately, performance of WordPress.org installations isn't usable so I have decided to get a subdomain.
I have access to the Akismet account, the email address, and the WordPress.com account, it just looks like the "alangurling" username can't be used to login anymore, nor can it be used for a domain/blog name here.
I have tried both links and they are not relevant to my issue as I know all passwords and I don't need to recover both accounts. I just need to get alangurling released, or the domain be created in the account instead of having it as a username only for Akismet.
Thanks for replying anyway.
