    I don't understand it AT ALL:

    /^[a-z0-9][a-z0-9\.\-_]*$/i

    And I don't need to... I just want to modify it to allow spaces. BUT not only spaces, just like not only _ and - (that should be there already). So Spaces with characters and numbers only. Can it be done?

    How could I make it allow only ONE space? And two? Both versions please, if possible.

    Try this:
    for one space:
    /^[a-z0-9](\s?[a-z0-9\.\-_]*|[a-z0-9\.\-_]*\s|[a-z0-9\.\-_]*\s[a-z0-9\.\-_]*)$/i
    for two spaces
    /^[a-z0-9]((\s\s)?[a-z0-9\.\-_]*|[a-z0-9\.\-_]*\s\s|[a-z0-9\.\-_]*\s\s[a-z0-9\.\-_]*)$/i
