How much room is there after an offer? (Atlanta)

I want to negotiate but I am afraid they will withdraw. There are 11 people counting on me, so I am trying to be careful. The benefits are decent.

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.

Thanks for writing this out. I went through something close to it 6 months ago, and it got easier once I kept a simple log of every call and form.
