Hi to the ghosts that haunt the hallways of technicalc.org 
I just wanted to say that if you have tried to contact me by email and not gotten a reply, my spam filter probably erroneously filtered your message. Please try to email me at BhuvaneshBhatt@gmail.com, or post here at technicalc.org.
Another thing... I would like to encourage modification/reuse of MathTools. If any of you want to extend/modify MathTools or package all or part of MathTools with your program, as long as the resulting package is free for everyone to use, please feel free to do so, but I would appreciate an email letting me know about it, and of course some sort of acknowledgment in the package's documentation. If you are planning to sell the package, that's probably ok too, but please email me first just to make sure. I'm actually kind of disappointed that no one has written another MathTools-type package that is newer and better and more powerful than MathTools. Although MathTools is a big improvement over my earliest programming attempts (I tried to do tensor analysis by using string manipulation!!), there are many things that I would now do differently, and there are a lot of ways in which it could be improved/rewritten. A few years back, I was actually planning a major new version of MathTools, but when I was just about to release it my hard disk crashed, and I had no backup system in place back then, so I lost almost all of my work. Among the improvements was a faster Groebner basis program with a wider choice of monomial orderings, various polynomial algebra functions, a more powerful symbolic PDE solver, more special functions, expansion of functions into Laurent series, series convergence testing, domain membership testing (is a given expression a member of the rationals, reals, algebraic numbers?), some linear algebra stuff such as Hermite normal form, lattice reduction via LLL, and modular linear algebra. That's all I remember now, but there was a lot more, plus quite a few bugfixes. Rather unfortunate that it all vanished, but that's life.
