To make this as short as possible, the username Vss2eip didn't really reflect my personality well - plus, it's meaningless. Although I'll still use it for most sites, The Sims Wiki isn't one of them anymore. I contacted Wikia about changing my username, but I don't know when will the change take affect.
The username won't surprise many - I dedicated it to my love of guinea pigs, and it's going to be Cavia porcellus from now on. For those who don't know, Cavia porcellus is the Latin name for guinea pigs. I wanted it to be Cavia since the meaning is the same and it's more simple, but it was taken already. :(
