Hi guys,
I wish to make a site which works as follows .. users can contribute music, gets paid 80% of the cumulative sales value at the end of the month if it's above a threshold. (All payments made via paypal)

Are there any modules available that can help me make such a site ? Alternatives to joomla would work too.

Thanks in advance guys..

I don't know Joomla unfortunately, but the Drupal ecommerce module lets you sell downloads and has paypal integration. I don't know about the revenue-sharing part though. [drupal.org...]

I would guess there's something similar for Joomla if you hunt around (and there are probably other modules for drupal too that would do it).
