Thanks for your response!
Do you have a sense of what the subscription feature may be? Don't mean to sound dense but, for example, if a user at a site subscribes at a certain fee, they can have "x" amount of listings, this sort of thing?
That would be good as it would allow users of the site who have a lot of relatively inexpensive items to list a bunch of them for a single fee rather than going through the PayPal route 10 or 20 separate times. Again that or a method that allows multiple items to be added then paid at the end.
Either way would be ok. I'm really kind of stoked about this software and want to use it in tandem with my existing site soon!
