Kernos has installed the new birthdate module and, because it doesn't allow for blanks, everyone appears to be 36! Please go into your profiles and enter your birthdates--you don't have to show your age if you don't want to--just check the "Hide your age" box.
Also, we have the gender field back. At the moment, we are all "not specified" and no gender shows in your profile. You can leave it that way or specify male or female, but I don't think you can return to "not specified" if you do specify one or the other.
Please don't get upset about this--it's completely your choice whether to show age or gender, and a lot of people wanted the options to be available.
