I'm looking forward to building an online store and nopCommerce seems like the right way to go. I would like to make my own theme and extend the code to handle some requirements specific to my store's domain.
nopCommerce is released under a variation of GPL-3.0 license and as I understand it, all code linked with GPL 3.0 source code must be disclosed under a GPL 3.0 compatible license.
My questions is: Do I have to make the source code of my store available to everyone? And by "code of my store" I mean, custom themes, pages and code that handles specific domain requirements.
