Hi! Just wanted to put out the following:

Cool additions so far! We're building something really great here, and I want us to incorporate as much of them as we can. The best way to make sure that your additions make it into the continuing collaboration is to UPLOAD YOUR ELEMENTS SEPARATELY!

Instead of uploading one single record of your stereo mix, make an album instead, then inside that album, include said mix of all your elements, AS WELL AS files of whatever new elements you have added naked, without the rest of the tracks behind them. Just turn off all the 'other' tracks and render a version from top to bottom of the solo item in question...Repeat for other elements as necessary. It's OK to have lots of 'dead air' if it's an element that only comes in briefly. This will allow us to play with them further.

Huzzah! Let's keep it going!
