Welcome to the game as well as the RPC Alan! It's always nice to see another Wyrmrest Accoridian joining here, I played on there myself (and still do a little), but the rp has lost it's charm a little there for me without much to do with myself. The RP community here is wonderful, very welcoming and engaging, I'd encourage you to never be shy if you see any of these fine people out playing and want to join in. Myself included!
While I'm not a seasoned vet maybe I can clear up the Linkshell confusion for you, Linkshells are like custom chat channels were on WoW, think LFRP, except that the leaders have to invite you to be in this chat channel. Now Free Companies are the equivalent to guilds complete with leveling them up, getting perks from doing so, etc. The linkshells offer only the benefit of chatting with like minded people, or in most cases, finding RP or dungeon groups, etc. Make sense? It's essentially just a specialized chat channel that is used for both OOC or IC chat depending on what the owner has chosen the functionality to be for it.
