You have to have the original game files either from the disk or downloaded from GoG or steam. Then you need tes3mp which runs great on linux and windows. I personally play on a server called neravarine prophecies, they have seasonal events and the community is a lot of fun. It uses the same engine as openMW so most of the mods that work on OpenMW are compatible, I'd stick with cosmetics to keep the servers you join compatible.
Different servers have different rules, many of them forbid going into areas that cause server crashes, i.e. mornhould.
I had a blast, then I got my kids to play and i was there to guide them a bit when the game gets tough.
so if you try to replace this yourself it turns out you have to jack up BOTH SIDES or the sway bar will be under tension and it will be hard to pull the link out. You can raise or lower the opposite side a bit to get it just right. the dudes on youtube that have a lift might not even think about how the car needs to be lifted evenly. I use arch btw.
