Just wanted to say i've made some suggestions before and some of which are incorporated, and whether or not i was the only one for suggesting these, thank you for that, as well as for all other improvements i like the direction Shapeways is heading. i thought about an affiliate/referral program. I think it would be a nice feature, for as much as i like the creativity and ingenuity behind successful marketing, i prefer to design. Marketing takes a lot of time, specific skill and persistent effort. I believe that's a paradox many designers have to face. I'm not weary of updating all outlets on which my designs are offered to the public, and increasing my visibility, that i see as completely necessary and my job, even fun and exciting since i'm always anxious to see which newly printed designs 'catch on' and which don't. However there's of course a difference between publishing your newest designs and successful full-time marketing. Ideally the system would allow to: let shop owner add an referral agent track which referral agent sold which item to a customer let shop owner add an email / paypal / pickup address of the referral agent (or give agent own login interface with all necessary options) let shop owner set universal item fee be it a percentage of the markup or a certain nominal amount for the referral agent inform the referral agent of any updates to the referral fee (in nominal value) per email periodically (biweekly/monthly) inform the referral agent of the referral agent' balance add the fee to a virtual balance which pays out until it reaches $30 Maybe the system can be made implicitly by use of the coupon code system, in such that the 'coupon code' instructs the system to add an amount to the referral agent' balance. Optionally, the agent may function as a distribution hub for countries where customers find the $20 shipping rate steep and distribute shipping over bulk orders. Let me know what you think.
