In this thread, there is some discussion about a possible name-change: L-girl becoming laura k. I thought I would try "laura k (aka L-girl)" for a while, then drop the parenthetical.
But now I see that if I change my blogging name, it changes on all posts on the entire blog. I should have realized that, since the new, more stable Blogger templates also appear on all posts - meaning, from the beginning of the blog until the current post.
I like the idea of being laura k in the present and future, but I don't want to erase L-girl from the past. I may change back.
