Send a message to HyperPete, he's a moderator and might be able to help. You can find him on the right side of the forum where it says "community staff". I think it's called having a conversation now instead of messaging.
I will take a look, but it may be an @M109R admin only task.
Note: Since you are using Askbubba now, it's not likely (in my opinion) that your old account exists if that was the username. Still, I will see what I can find.
Sorry, @askbubba, but There is nothing that I am able to do.
I did a complete forum search, and there are no old posts from anyone named askbubba or askbubba0, or even references to either of those usernames. Perhaps you can find the details in your old email.
You can ask @M109R admin if he / she has any tools to find your old account, but without you even knowing your old username, I would say that it is extremely unlikely.
If you know the old email address, you can login with that instead of your username. Using the forgotten password link will send an email with a password reset link.
It is also possible that they database was purged during the upgrade to the new forum password.
I am unable to change the email address on your accounts. There were only 3 posts made in that account. Unless @M109R admin can somehow merge your accounts or change your email address, I am afraid you are out of luck.
