Matt James has organized a great collection of Forgotten Realms authors and game designers to answer all your burning Forgotten Realms questions at
www.loremaster.org.
The perpetual interview lets you query real masters of the Realms lore like creator Ed Greenwood as well as some Young Dragons like myself. Check it
out.
Matt will be adding more people as the months roll along and he likes getting suggestions too. So be sure to let him know who you would like to interview!
