I've stopped using Hotmail and Outlook (horrible) years ago when I switched to gmail. It's sheer genius.
Forwarded all my email accounts (and I have LOT of them) to gmail, so it's all in one big inbox, and accessible from whatever computer I happen to be on.
Could not live without it.

Put the new email sig at the bottom so folks will pick up on it AND send everyone a notification email about it. People tend to not notice anything that dissapears under the fold.
