My numbers mess up from time to time but I don't let it stop me from coming in. Alot of websites don't have this feature for example NAMI, DBSA, and so on. So when the numbers don't work here I just chalk it up to psych central being like a majority of other on line sites that don't have this feature and instread of numbers dictating which threads I read, I read the ones I want to based on suject line titles. It may take more time but I manage elsewhere without having this feature so I don't depend on it here either.
