Step 1. Go to your MSN/Hotmail e-mail inbox and click on Options(in the top right corner of the page)... and then, more options.
Step 2. Under the header Writing email, click on Message font and signature.
Step 3. In the box under the header Personal Signature, enter the text you would like people to see(and that will link to your website URL).
Step 4. Right-click and press select all.
Step 5. Once the text you would like to convert into a link is highlighted, click on the Insert Hyperlink button(it looks like planet earth with a link).
Step 6. Simply enter the website URL you would like to link to and click on Save.
Voila! You're done!
