I find the basic idea good - would consider balancing it with another as the g in .org. You have the layout of "The Newt and Salamander Portal" to consider, though.
With the stylized (oh I read once what it actually is...?) green and orange salamander currently in the logo, you would have a higher "brand identification" of the logo - and the logo is easier to reproduce on pockets and keychains.
Two cents, please.
