"Hello! My name is Eric, and it's my pleasure to welcome you to Wikipedia, the free encyclopedia. I've noticed you've started making contributions, which is a great thing! On that note, I'd like to invite you to create an account. You don't have to log in to read or edit articles on Wikipedia, but creating an account is quick, free, non-intrusive, requires no personal information, and gives you many benefits, including:
The use of a username of your choice
The ability to view all your contributions via a ""My contributions"" link 
Your own user page 
Your own talk page which, if you choose, also allows users to send you messages without knowing your e-mail address
The use of your own personal watchlist to which you can add articles that interest you
The ability to rename pages
The ability to upload images 
The ability to customize the appearance and behavior of the website
The eligibility to become an administrator 
The right to be heard in votes and elections
Your IP address will no longer be visible to other users.

We hope that you choose to become a Wikipedian and stay for a long time. No matter whether you choose to create an account or not, I hope you will continue to be a productive (not destructive) member of our community as we strive to make this one of the greatest sites on the world wide web.
