Well, I went to see my agent today to set up my plan. I can offer another resource for those in California: Covered California's phone number is 800-300-1506, and they'll help you find a local agent. (I have no commercial relationship with these people other than as a client.) It was a lot easier having someone who was knowledgeable about the system to help navigate our way through, especially when we ran into a glitch. (Because my husband was honorably discharged from the military, for some reason the computer decided that meant he wasn't a citizen--go figure.)
She told me there's a help button on the right of the government page, and for those outside California, most states have some sort of assistance program in place, usually at the county level. But it's best to get to it quickly, since the short deadlines mean everyone's going to be swamped.
