Beta Patch today in an hour approximately—hopefully the character renaming and beta installer get a fix.  Not yet confirmed.

Nethaera: All beta realms will be taken down at 2:45 PM PST for maintenance and a patch. We expect the downtime to be approximately 5 hours.

Thank you for your continued participation and feedback in the Burning Crusade Beta test.

We also anticipate that this will fix the Character copy issue. We very much want to have this resolved as much as everyone else and have been working on it.
