Secondlife is a wonderful and strange game. It has a long history of hosting all sorts of internet freakazoids across the ages, but i've only been playing it for a couple of years. I find a lot of joy exploring the delapidated remains of old sims, along with the new places still bustling with life despite it all. My favorite part is probably avatar creation, so this page will focus on that a lot.
SL can be played with many different clients, also called 'viewers'. I used to use Firestorm, but now I use Alchemy. That is to say, both of them are decent.
Me and my friends own a small building known as the RPGMaker Clubhouse. Stop by and say hello sometime.
