Rare fruit newsgroup? Exist?

[Leo Manuel]

I live in San Diego and like to grow fruit trees and fruit vines. 

I grow the exotic ones such as mango, banana, cherimoya, guava, 
macadamia nut, kiwi, citrus, passion fruit, and the more common ones 
like apple, plum, grape, peach, nectarine, etc.

Does anyone know of a newsgroup where more of the 'rare' fruit trees 
would be represented?

Thanks!
