I have not bought a server yet, but I am planning on it. Before I do, I would like to know if I can operate mods on the server. I am ultimatly wanting to run The Dark Trilogy modpack on the server for a Let's Play. Is this possible?
Yes you can run custom jars and mods. https://www.hosthorde.com/forums/resources/installing-feed-the-beast-modpacks-1-7-10.87/
