Change of email address - I am fed up with Gmail

I have been getting nothing but spam from my Gmail account lately. It's nearly the identical spam message being dumped into my spam folder (so, now, I have 2 folders of mail to search through instead of 1 on a regular basis), and I've gotten 80 of these in the past month. Gmail marks each message clearly as spam, but still dumps them all into my account anyways. Why not just block it if it's spam? Well, they don't have a way for me to block emails. Such an ineffective webmail service in the middle of 2006 is not acceptable, at least for me.

So, I've established a Yahoo account for my non-personal email address.
