I've asked similar questions before but here goes:
One of the players in my main group is moving, I've been saving for a nice in person table but since we likely won't be meeting in person much anymore, I've decided to allocate a portion of those funds to a tailored Foundry set up for our games. I've decided to go with 3rd party hosting for the sake of uptime and maintenance but I'm also aware that the modules I'm installing require some custom scripting on the backend to make things work 100% how I want them. Can anyone tell me what kind of scripting language Foundry's module's use? Is tweaking them particularly difficult?
