Final Fantasy XIV: Legacy credit application site

UPDATE from Square Enix: "In order to better cater to members of our global community, we have raised the character input limit and expanded the variety of acceptable characters when registering your name for the Legacy Credits. Please refer to the registration site for details on the new character limit and types of characters that can be used.
Players who have already completed registration may do so again if they desire. However, only the most recent name registered will appear in the Legacy Credits".

If you're a Legacy FFXIV player, you can get your name in A Realm Reborn's credits. The website to do it is now online, and you have time until April 30 May 7, 2:59 pm (GMT): click here. Will you use your character's name or your real name?

UPDATE: More info from the official FFXIV forum:
"First, all names will be accepted at first, but if we determine that a certain name cannot be used, we will send an email to the address registered to your Square Enix Account after the registration period is over, asking you to re-register. 
Also, in the event that multiple people enter the same exact name, it will only be displayed once. For example, if 10 people registered “Naoki Yoshida,” this name would only appear once."
