I am New to Ypops, help

[nipnapcreations]

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.

Thanks.

YPops has not worked for me in over a year. I think the last time it did work was in October 2009. Yahoo changes things to keep breaking YPops, and there is usually an update that follows that fixes things. Unfortunately, no update has come since the October 2009 Yahoo change. I have yet to find a solution other than paying $20 per account per year for direct Yahoo pop access.
