Are there statistics of ET registrations vs longivity? Frequency of new registrations month by month or year by year versus frequency of logins. For no particular reason other than wondering if it corresponds to a gauge on how many new traders stick it out. (Survive). For instance new registrations 2019 and current logins in relation to 10 years ago registrations and those members still posting/viewing ET. If it were possible to screen out those in the political forum as it appears some don't trade.
