I like the idea of including an info link to cd sales info.
There is a link listed above in the drop down menu, the Mudcat Market, that mentions other talents by certain members. It seems that an additional page could be added so that when selected from the drop down menu it would include member cds available for sale.
I think that a percentage going to the Cafe for such a service is a good idea, unless it would alter the status of the site in some negative way. Most every other outlet for such sales takes a percentage.
