Thunderbird set up
 

I am trying to just get my Thunderbird to set up properly so I don't have to check 4 different emails all the time. I can't get the emails from the other clients...I have read up on 3-4 tutorials and I can't get them to work following step by step instructions. I have the accounts on there and Thunderbird recognizes them and prompts for a password but then will not show any of my emails etc etc.

OK i have Gmail working ....but I am still having a hard time with Yahoo and my school email account. so ANY suggestions there would be greatly appreciated
