I'm sorry, my micro has broken and I don't have much online time, but I posted about the subject twice the day JKR "outed" Dumbledore.

There are many good posts and articles on the subject, but I have no time to search for the links.

Here's an article saying that it doesn't matter, because it's not in the books:
