Seems there is only the guided format for entering new bugs. Although it is useful to people that are not familiar with bugzilla, I'd rather have the simple form without the explanations. Just cause I feel so pro ;) Reproducible: Always
There were lots of requests for the footer to be the guided format by default. The expert input was always on the front page, so I gather you didn't look there. I've tuned the footer a bit more now to have an expert input, but I'm worried it's getting too long.
I found the link on the frontpage after filing the bug, but i still think it should be in the footer. If you want to save some space, you might want to remove the 'my requests' link. I couldn't ever figure out what the whole request thing is good for, I guess it's somehow disabled in our bugzilla.
