My changes have been around for almost 10 years, and are more widely used. Your changes are very new and unstable, but don't really solve the needs of people using my series. I've tried to work with you and I take comments from you, but yet you insist to submit your own series. I would suggest this isn't going to go anyplace unless we work together. I can't really support your changes because, honestly, your changes are really ugly and they just look more and more like my changes with every passing iteration .. As the maturity of your changes continue they will just become my change set. I've been thru every iteration of these changes, and I see those attempts in your changes. Everything different in your changes I've tried, and found not to be useful, then it falls away in later iterations. When you give me comments on something which I haven't tried I typically incorporate it. Daniel
