I made a discovery today,
I had several habbo accounts that i previously made way back in 2002, and since then i had forgotten the both the old habbos' account's passwords and the old email address's password i used.
Because I hadn't used the hotmail account in 6 years, hotmail obviously deleted it, which meant that there is no way to retrieve my old accounts back. (as i need an email address to get the passwords etc)
Though habbo keeps your old email on your old account on file. I recreated my old email address today (as it became reavailable), and sure enough, I requested Habbo to send me account information and it worked.

Ill be able to get back on my old accounts again, and get the three thrones (hopefully) that are waiting
If you have the same problem, you should try it.
