well might i ask that in your next version you include a paypal IPN script as part of the Classifieds application and pass that url as a variable with the transaction. I know it can be done and it would allow this app to be used with other paypal enabled apps, such as vbulletin itself.
I'd love to run this, but i already use my IPN for vbulletin and for my own home grown add software.. both with passing a separate IPN url ..
thanks for your answer though.. i'll keep watch and wait to see if that is integrated.. or i might code it myself if i get desperate enough.. hehe
(want a copy if i do ?)
