Thanks for the good questions, folks.
The rules do state that a seller should indicate country of origin. Where they ship to is up to them. If they choose not to state it and have to deal with clarifications from buyers, that's their choice. Any rational buyer will ask a seller that is outside their own country if they will ship to them.
So yes, about PayPal fees, it is not appropriate for someone to say a pen is $XXX and that the buyer must add 4% on top of that if paying by PayPal. If you see it, please report it.
Regarding the minimum 30 days and 30 posts, we are working to put this into effect via a website function. We instituted 30 posts by the majority vote. If it turns out that it's not enough to keep "sell only" type members from joining, we'll raise the minimums as needed. The main issue has been keeping the volume under control. The marketplace is now the most active part of FPN, which was NOT the original intention.

It seems we're getting a lot of overflow from "that auction site" where fees are rather high.
As for images, we've had this as a requirement for quite some time -- it's not new. We've just made a clarification on what we expect for image sizing. If you have a film camera only, then take your pictures, get them developed, and then scan them in for the electronic image equivalent. The whole reason for providing images is for protection of the seller... that the buyer can't make any claims about the pen being the "wrong one" or having any glaring discrepancies from what was described. You can take fairly decent photos with many cellphones today. Of course, some phone cameras will be sub par, for certain... but then, it's all a matter of whether the seller feels they can get the price they want based on what is shown. The better the photos, the greater the chance of a buyer willing to pay the asking price. If you don't have a digital camera and plan on selling pens on FPN from time to time, consider buying an inexpensive digital camera. Many can be had these days for very little money.
Thank you for all of the positive feedback. We're glad to see that most people appreciate our updated guidelines.
