we'd like to send to do a brandfree option but don't know where to submit a payment so we can remove it.
We are now offering a branding-free option that you can purchase if you want to remove the "Designed by Brivium LLC" branding in the footer. The price is $30 and gives you the right to remove the Brivium branding from one (1) installation of Hydrogen style on one forum. This is a branding-free license only. Purchasing the branding-free option does not entitle you to extra support or priority support. We will try to answer your questions as best We can here in this thread, but in terms of support you are no different than anyone else.
Branding fee for premium addons are same with addon price. That's mean to remove copyright for 3 addons you need pay for total price of these. On addon description page we provided information for copyright notice. Please check again. Regards,
