Authoritative Minesweeper

I just realized that the birthday field in the minesweeper.info profiles can't seem to be edited from the fields available after login. I personally don't wish to put my birthday online, but I would like to at least put my birth year. How do I do it?

only damien can edit these fields in his database.
->email him and prepare to wait 2 months

or...
just write it in your bio. actually this seems to be the better option, since it would allow you to change it as you like.
