[jbv at souslelogo.com]

Hi list,
Does anyone have any experience with open source marketplace software ?
I don't mean regular ecommerce website, but Open Source Multi-Vendor
marketplace software.
There are several solutions available and would appreciate if anyone
would like to share some experience on this matter.
Please contact me off-list.

Thanks in advance.
