I would like to add a `realName` field in addition to the user's user name and email address. 

In the past I have created a new table that includes the `username` and `realName` columns when a user registers. However I would like to know if it is possible to extend the default asp.net forms authentication membership table or user table (or whatever table is necessary, to add this to) instead of creating a new table for this information.

**Question:** How can i add a new column to authentication tables?
