The iPod and iTunes forum has become the iPod forum and moved from the Apple Hardware section into the iPhone, iPod, iPad section.
iPods, iTunes, and the iTunes Store were originally focused on music. These days iTunes and the iTunes Store cover much more territory so it makes less sense to tie their discussion to iPods. iTunes is an important application but so are other Mac OS X applications like iPhoto. We'll use the Mac Applications for them all, so we've moved threads about iTunes into that forum.
Where to post
For discussions of iPods (nano, shuffle, mini, classic) and iPod accessories, use the iPod forum.
For discussions of iTunes and the iTunes Store, use the Mac Applications forum.
When in doubt, take your best guess as to where others would look for your thread. We know that some threads will fall into the grey area, e.g., questions about syncing an iPod to iTunes.
