I wrote a bug report. When I clicked the Upload button, I was shown a registration form. (So far, so good.) I registered, it told me the registration was successful, so I clicked Upload again. It told me "You must confirm your email to upload content", and here's the bug: it discarded my bug report. I hate to write it all out again and take the screenshot again.
I think this is a serious bug; it may have quite a large negative impact on bug reporting. Bug reporting is not easy for me, and I have at times given up on things entirely over obstacles like this. I know I'm not the only one.
Sorry for the annoyance, we'll look into this in future updates, thanks for the heads-up :)
