ECL for a Silver Dragon

[astralpwka]

Question for somebody with the Draconomicon...

I know that the ECL isn't covered in the book (which I don't own yet), but is it possible to figure out the ECL for a Young Adult Silver Dragon? (say age 51).

Any information on creating such a character would be appreciated.

Ouch... I posted the same thread twice. Can a mod kill one of them?
