Oh were you using the drop down menus above your portfolio items? Those actually haven't been coded yet. But when they are it was only intended to sort within your portfolio manager. I'm assuming you wanted control in actually sorting your submissions around the site for the viewers. i.e being able to change the order that they appear on
your portfolio.
Definitely something I think we should do, and it could be something nice like a drag and dropable interface. We already have features utilizing drag and drop for ordering data like in the profile
Social Networks, of which both Digg, and Pownce can be found, so it should be a cinch

Edit:
Alright, I just played with the Portfolio Manager a bit, I updated a buncha' stuff, Title, Description, Category, Tags, permissions, licenses, and cropping, all seem to work fine, the only thing that is really acting up is the "Styles". Need to look into that.
I also need to write some detailed docs on the Portfolio manager, and submit tool for new users. It's pretty complex stuff, and many options.
Thanks again!
