I read the license, which is why I'm writing directly to you. You have several packs marked as "free". We are a well-known website in Poland dedicated to RPG Maker engines. As one of the editors, I noticed your work and thought I could promote it a bit on our site. The chief editor gave the green light, but he asked me to check with you if we could upload one of the packs marked as "Free" on our website.
As a site dedicated to RPG Maker engines, we have a resource database and the ability to include links to the official store. Our users often want to download a sample before deciding to purchase graphic packs.
For you, this could mean an additional audience for your work, and for us, having permission to upload even one or two free packs would be a great way to expand our resource base. I was thinking about the packs tagged "free".
Of course, if there is any obstacle to promoting your work with already freely available packs, we, as the editorial team, will understand.
