Search engines did not locate any advice for me, nor any way to ask for tech help with the website.
I also had trouble, a year or two ago, trying to email the IRS through their website, and finally figured out that the problem was that my favorite email address' URL has a hyphen (minus sign) in it, and that was being rejected as an illegal character. I tried the whitehouse.gov sign up again, using a phoneco/ISP variation of my email that has the same username and comes to the same account, but the URL has letters and (dot) only.
Success. I got my email with the new password almost immediately.
I figured I should post my discovery to help the next confused person searching for "no email whitehouse.gov".
By the way, the list of petitions is at
It can be hard to find the log in at whitehouse.gov unless you go to the list or have a direct link to one of the petitions. The log in link is at the bottom right of the petition screens, in a dark blue bar, as of September 2011.
I encourage people to become politically concerned and active. Your fellow citizens need your responsible support. KGHN
