@ Loquacis - I felt the same way! I didn't get an email confirmation at first and was kind of freaking out, but I did get one eventually.
If you feel weird, maybe give it a week. If you still haven't heard anything, it probably wouldn't hurt to send a quick note asking if she received it. I did that, and Sarah was really nice about it. I was kind of scared about looking like a typical, nervous writer, but it was cool.
@ Mairi - I will! At the moment, I'm in revisionland, which isn't terribly exciting, but it's a nice place to be.
