Fucking Yahoo

If you can't make your fucking upgrades work, don't fucking install them! So far I have spent 20 minutes trying to read my fucking email in Yahoo. I keep getting those DNS errors. PLUS! I belong to a couple of lists where I get daily emails. One ALWAYS goes to my spam box. Despite my having added it as a contact AND the clicking of the 'this is not spam' box. What is the point of having these two options if they don't work?! Fucking yahoo.
