Just logged in to Test to see what happened with the chars. I have 7 on Test right now, and am showing only one from Shidreth when I should be showing *cough* 8. No scrolly option available to select any other chars, if they're there. It seems to be showing the char with the lowest alphabet name-starter - just my luck she's one I don't even really like.
Edit -- ok this is apparently WIA, so ignore.
For post-record however, trying to log in the one I could see "Alix17" resulted in the expected name-change box. I gave her a first name and a last name, hit Accept, and she vanished from the char list to be replaced by the next alphabet starter, Eloise17. I tried it again, still not changing the initial, and am now down (?) two and on to poor Fairuza. Won't mess with any more since we're getting to some of the characters I actually play occasionally (rather than the ones I'm keeping for name purposes till after the merge :P).
