I completely understand where this is coming from, but . . .
one of the "bad" examples was:
I do (did) provide links to demo's for some of my extensions, so potential buyers can see better how the extension works. I have never, however, offered them at a lower price. Is this allowed?View the demo of the templates at this link: http://www.xnetus.net/template/temp0845/
If not, what about screencasts? Are they allowed (bearing in mind an unscrupulous developer could also use this method to advertise their product cheaper elsewhere)?
Some clarification on this would be very helpful
