I wonder how I can set up the registration so they have to have TWO NAMES in it? I can't guarantee that they are their real names...but I want names only and no numbers permitted in the registration.

Use custom fields, possibly 2 of them (first name, last name). I think you can control it so that they can only use letters. You CAN make it so that both fields are required to be filled out.

And this either needs to be done in the above method, or using a mod. Its not somthing most people need or want.

I think it'd be nice if we could have the option of using regular expressions to regulate what is acceptable in the field. That way fields such as real names could be better enforced (although not perfectly).
