Joined on the 31st of January 2008 on this avi, a month later on my alt. It was with my RL (now ex) partner at the time. Figuring out how to escape the clutches of Orientation Island, and Help Island, wasn't that hard. I've been a gamer since childhood, and almost every game on PC has its world map keymapped to either "Ctrl + M" or simply "M"--it was a logical assumption that SL did the same. Then we discovered the search.
So some of the earliest memories involved searching places like Freebies Dungeon (is that still around?), and I think another was called Neva Naughty or something. Also going around clubs such as Bad Girls and The Galaxy, along with one or two Neko clubs that I forget the names of now, and other random rock/metal clubs. Entering contests--and that's basically how I earned my L$'s for several years, to fund "better" skins, hair, clothing, naughty bits, and such. I was raking in L$2-4K a day just from that, depending on my mood. Eventually "retired" from doing that around 2012.
There are far more memories, but I'll save them for another time.
I sometimes go back to the Help Islands. It's somewhat fascinating to see people go there, still with system avis--and I'm talking 2004-2006 style system avis. Even though said residents may be a lot younger. I almost feel like a paleontologist when I do visit.
