>>>Also, be aware that making it obvious how the "user" file works it not good security...in other words, if you simply have a USERS.DBF file with one field called USERNAME, and in the file is simply the names of authorized users, then all an un-authorized user has to do is get into the file, add a record, and add his/her name....I think the easiest way to do this would be to encrypt the username...so if someone looks at the USER file, they won't know how to add themself...just a thought...

thanks Mark for the information - I will look into it.
