Amusing myself for a few minutes, I googled my online handle izhilzha. Among various other things, an online newsletter called "Firefly Talk" came up. In Issue #4, the Fanfic Review section contains just one entry: Flying Lessons.
I got recc'd on a newsletter.
I am dazed by the fame. *g*
That's all; as you were.
