I find the subject confusing. You're in the same class, but you don't know who she is? I guess she PMed you or something?

And yes, it is very annoying when people change the title of a thread a thousand times. People do it all the time though. I have done it before, though usually not for the purpose of tricking people to click on an unloved thread. I usually change it when something important had been added to the thread...

Anyway, who cares?
