I'm using Visual Studio 2013 VB.NET and Web Forms.
I need to allow the username to be as short as three digits while also allowing an email address to be used as the username.
I don't think this is would be too difficult, but every example and documentation I come across is in C# (which I prefer that syntax over VB which is fine) and is in MVC. I do not know MVC and I also have zero experience when it comes to security.
Any help would be appreciated.
