She's not doing Regular Checkups anymore. ;-; You can still see some of your "Stats" by clicking your Summary in your profile. That way you can see how many posts and topics you've read, but unfortunately not how many you need to read. An easier way to earn Regular back is to click the 'New' tab at the top of the forum and browse through all the new topics there! Also, if a topic has a blue dot and "new" next to it, that means you should click on there too. Most people who are demoted from regular haven't read enough new topics. I find myself getting demoted often because of this.
I'm doing this right now, actually! :3
