I'll second this. P2Forge is a fantastic app for anybody adopting a P2 workflow. It's far better than either of the Panasonic tools (P2 Viewer and P2CMS), and it keeps getting better with each release. Robert, the developer, is extremely responsive to bug reports as well as to feature requests.
I like the automated transfer and error checking/verification that P2Forge does vs. P2 Genie. I think P2 Genie was a great tool at the time, but it's kind of stalled in its development. This one does everything it does, and much more.
