Don't get so hung up on "3 tier" and stuff like that.
You have a very specific problem you are trying to solve so just focus on that alone.
What you need to do is run a query against your database to check if a value exists. That's it.
publicbool UserNameExists( string username )
// Connect to your database...
// Run a query to check if username exists.
// NOTE: Use a paramatarized query.
// Something like: SELECT count(*) FROM [YourUserTable] WHERE [YourUserNameColumn] = @username
I wasn't, now I am, then I won't be anymore.
