Guys, you don't need to be asking for a forum for the Padfone 2 because;
1) This is the wrong thread to be requesting a forum be added for it. The relevant thread is stickied at the top of this very forum AND
2) One of the admins has already explained that a forum won't be added unless there's proof of strong development for this device.
If, as already suggested, there was an established CM maintainer who has got CM running on this device, then that would likely greatly increase your chances of having a forum created.
Also, don't say that the Padfone 2 will get more developers once it has a forum because that's a load of rubbish. The device is what intrigues/entices the developers. NOT whether there's is a specific sub-forum or not.
There is a Miscellaneous Android Development forum which is perfect for your needs as you can post any development for the Padfone over there.
