Email box at Gmail

I have been heard of good services of gmail. Tried to check out it, I tried to register at their site, but could’t find “sign up” button. Spending few minutes over there, I found out that it works� in beta mode yet, and to get an account at gmail you need to recieve the invitation email from pal who already has an account at them. Huh? maybe someone would send me this letter, please? at zaur@pdesigner.net
