Thanks, that's helpful. I'm surprised FF and Chrome are claiming there's unsecured content on the https pages. I wonder if it's Google Analytics doing that...I can't think what else it could be.
Adding a page that lists all our contribs is on my to-do list - definitely agree that that's lacking. I also agree that the trial needs to be more explicit, and we should probably upsell with more than just an email when the trial progresses/ends. The other suggestions you made were helpful as well.
Thanks for taking a look!
