For the most part these days I take on the role of my Master's ponygirl, which is a large interest of mine, though I have my breaks and times of being allowed to have some control over my own things. If you see me standing around don't feel to shy to come and say hi, I may not respond; many times I'm not able or just dealing with scripts or real life and don't see your message. In my pony form I have my bit in my mouth which makes talking hard and my earmuffs make hearing hard as well. IMs are generally the way to go.
What I know I share (for the most part) freely with those who ask, for a while I hosted a scripting class to pass on the knowledge that I've gained over the two years I've been in SL and while the class is gone my willingness to teach isn't. I may not always have the time, or the desire; we all get ups and downs, and lets face it, some people just can't learn even if they really want to. But there is no harm in trying.
But what about the person behind the pixels? I make little to no attempt to hide who I truly am, for the most part it just doesn't really matter because none of us will ever interact on a real front and the information becomes a waste of time.
And that, I guess, is a little about Lylani; and the girl behind her mask.
