I use the Web Security Application Tool (WSAT) to create new users, assign roles, setup folder security etc. when I just have a few to do or I haven't set up pages with CreateNewUser controls, etc. but how can I bulk load the first two thousand members that will be using the site when it goes into production?  I thought maybe that I could import them into SQL Server (the same user table created by WSAT) but how could I hash the passwords?  If I hashed them using SQL Server somehow would the ASP.NET security system "understand" them?
Thanks in advance for your insights.
And if there's a better way than what I have described, please let me know.
