We got a PP from Lauren and Alexis.
We got a signed and personalized pic from Keiko Agena (Lane)
We got a signed and personalized pic from Edward Herrmann (Richard Gilmore)
We got a signed and personalized pic from Scout Taylor Compton (Clara Forrester)
We got too many signed and personalized pics from Jared Padalecki (Dean)
We also wrote to all the cast, Scott Patterson and Melissa McCarthy and we got nothing

Yes, just like Nanci said. Gilmore Girls rocks! Good luck with your collection

Yes, just use the search bar to check for feedback and via venue feedback, and use the fanmail.biz toolbar for database searches

Well, your best option is to search Fanmail.biz for their feedback but I remember seeing several Keiko Agena (Lane) and Emily Kuroda (Mrs. Kim) successes and a few Edward Hermann (Richard Gilmore) and Melissa McCarthy (Sookie) ones a long while ago. Maybe you'll still be able to get one of them.
Just check the database for addys or look at official websites.
There have been a few Jared Padalecki (Dean) successes recently (He is in Supernatural now).
Chad Michael Murray (Tristan) as signed a few times aswell. He is in One Tree Hill now and signs when you request a castpicture from OTH. You can also try via venue, maybe former Gilmore Girls stars have new movies coming up.

Hope this helps! Good luck.
