One area that has caused a lot of issues in the past is the account creation system. And while this isn't necessarily one of the more glamorous parts of the platform, we felt that it was critical to create a simple, email based account system with all the normal support that you would expect for resetting your password, password recovery, etc. (This means that we have removed all Facebook and other non "standard" ways to login.)
We don't want to make this process difficult so our initial plan is that you will be able to create an account with a unique user name and a unique email address and quickly get into the game without having to do any additional verification steps.

That being said, one thing that we absolutely want to be able to do is to reward the people who have continued to play the game by detecting when an email from the old game is used in the new game. To do that safely, we need to make sure that players can "verify" their email addresses because we wouldn't want someone to steal someone else's email address.

So, the current plan (still subject to change) is that you will be able to quickly create an email based account and during account creation, you will be given an option to "verify" that email address. At that point, if you prove to be the owner of that address, we will be able to confer whatever reward/rewards that should come along with that account. (Of course, if you don't opt to verify during account creation, you can still do so at a later point in the interface.)

So, that's the plan. We are trying to walk the tightrope of new and old, and hopefully we will be able to pull it off.
