Apple Sanctioned Developer Forums
Hallelujah: Apple is now offering official developer forums for the members of the iPhone Developer Program. It’s tied to your Apple ID, so they know who’s in and who’s not, and part of the usage agreement implies that they may provide forums for the discussion of pre-release software.
I hope they extend this to Mac development, too. The Apple mailing lists are great, but up until Leopard was released, the moderators on cocoa-dev were constantly fighting the tide of questions about Leopard-only APIs.
