How to let Frontend users change products in the database

[jobmoving]

Hello everyone,

I've got FrontEndUsers installed and also the module Products.
Can i let my frontend users change products by a form?
The goal is to let people sell products on my website by
signing up and adding new products. The signing up and the products are already setup, but the link between them is still missing.

Are there any plugins for that or do i have to write one for myself?

Many thanx!

There is no module for that that I've seen...
