Yep, no signature.

She just uploaded it as is, no signature.
 
I'm trying to check it out as it was done over a month and a half ago, but the CEAC website seems broker today.

Definitely had that section (we submitted our DS-260 on Oct 20th), but it was buggy. We would fill it out and it would randomly disappear during the review process so we filled it again 2 or 3 more times.

Documents are not too hard, you can handle that yourself. It can get complicated if you have travelled a lot and need police certificates from several countries, but even with a lawyer you'll still need to get all those documents by yourself.
 
The affidavit of support is not too hard either, especially if your sponsor has a straightforward work history, earns enough and has filed taxes in the past few years.
 
You should call them about the consulate interview location if they made a mistake. If you need to change it (because you moved countries for instance), you'll need to send them an inquiry:

They'll need your current address, which consulate you want to have your interview at, and proof you're eligible to have your interview at that consulate (nationality, birth or residence in the area covered by that consulate).
 

Same here, we submitted documents last Friday evening, they were all accepted on Tuesday morning but a few others were requested, submitted the same day and DQ next morning.
 
That was a nice surprise, I was expecting weeks of waiting.
