Expertise:  My experience in mythology lies mainly in Greek mythology but I can answer almost. Such as who are the main gods in the Greek pantheon, what were the 12 works of Heracles, did Helen really flee from Troy with Aeneas? How are the family ties with gods and mortals.

Experience in the area
I have read more than 30 books on Greek Mythology, watched a lott of movies that were made about Greek Myths, and done research in museums and of course in Greece, Turkey and Italy from the Metamorphoses from Ovid, down to the Iliad and Odyssey in three different versions. I also own some more obscure books about Greek Mythology, that show a small basis of a part of ?The Lord of the Rings? for instance.

Organizations
All this knowledge I really got from reading Greek myths since I was 8 (at this moment I am almost 27).
