Hey guys, I got asked to set up a Garry's Mod server for a friend a while back, and I thought it was a total walk in the park... until I realized how many hoops you gotta jump through. So, I'm starting this thread for all the noobs out there who want to host their own Garry's Mod servers like pros. What's the most challenging part of setting up a Garry's Mod server, and what do you guys recommend for beginners?
