A great deal of information about Judaism is now available on the Internet, making it a wonderful way to begin learning. However, conversion to Judaism involves much more: study, worship and practice in the context of an active Jewish community. After the decision has been made, there are rituals that mark the new Jew's entrance into the convenant and affirm the community's embrace of him or her. Therefore, conversion over the Internet is simply not possible or advisable. To convert in that way would not be meaningful or fulfilling.
May I suggest that you contact a rabbi near you. I am sure he or she would be happy to meet with you and discuss ways you can begin to study about Judaism. If, after a period of study, you decide that you want to become a Jew, I am sure the rabbi would be ready and willing to explore that option with you.
I hope that you will learn more about our faith and that you will, indeed, make the decision to become a Jew. I look forward to welcoming you into the Jewish people at that time.
