It has gotten to the point for me that I can't just hit the "use new identity" button. I used to always dp that if I had been idle more then 10 minutes. But for a couple weeks now I have gone as long as 4 hours and can not log in. Now I just shut down and restart Tor. It has worked every time until today where I tried for 4 hours to get online. I know it sucks but a small price to pay for this site.
