I need only frontend submission plugin or I should first have easy digital diwnloads and then have frontend sumbission on it? I mean does frontend submision works standalone? If so, where I can find it?

Frontend Submissions is an add-on for Easy Digital Downloads, so you need both.

So, I need the plugin easy digital downloads than I should add frontend submition on it? Already throu my admin panel? Where can I get step by step instruction to have frontend submition installed? Hiw much will it cost me overall? Price is for lifetime or for limitted time?

Hi Pippin,
I’d like to buy today this extension but please confirm that is possible the users to set-up their own payment gateway.
I saw all photos but there wasn’t an information about the payment. Also the link above with the complete instructions is leading to 404.
Thank you for your time!

No, users cannot setup their own payment gateway.
