Okay, I heard about YPOPS and Easy Email Forward from a CNET video, tried it all out, got confused and nothing worked right. So, now I'm back at square one. I am not hugely computer literate, but I am trying to learn. I have a main gmail account that I want 4 other old/new yahoo accounts to send/forward/import/whatever to. I was reading about using Mozilla Thunderbird, and Ypops or some Mozilla Thunderbird addon, (I will post links below) but as to all the server, host, SMTP, and other such, I have NO IDEA what I'm doing.
Could anyone offer any help or link me to a step by step way of getting this? I couldn't get YPOPs to work so I am looking for another software that does that, and Easy Email Forwarding failed on me too, so that is out of the question. If it matters I use Windows Vista and I stay in the US.
