This should serve as a caution to everyone. Don't get into a code posting battle with Neo, because he will continually pester you with minor little changes and challenges ... all for the purpose of showing off his thing (otherwise known as blatant marketing). He has already demonstrated with Hugo that he has no integrity and will cheat to gain advantage. Not to mention his propensity to distort accepted database concepts to his own ends (e.g., redundancy).

Neo, your challenge is respond to substantive issues such as those I raised in this thread about MultiValue attributes ...which your thing supports.
