I am an adjunct professor for the University of Arizona where I teach one of the largest personal finance courses in the country, with over 500 students per year. I also teach advanced personal finance, corporate finance, and investments. I hold an MBA from the University of Michigan and have completed all coursework and written exams for a Ph.D. in finance from the University of Arizona. I am currently involved in a long term dissertation project involving lifetime investment strategy. In addition, I am president and co-founder of National Personal Finance Education, one of the country's largest online U.S. Trustees approved providers of a personal finance course, designed by myself, which meets the requirement for bankruptcy filers under the BAPCPA law of 2005.
I edit and improve most of my posts after I initially place them. I will not hesitate to do this, and without cross-outs, as my main goal is to teach and discuss clearly and well, to help with discovery and good idea creation, not to leave a historically accurate evolution of my writing. In fact, if you think the writing of a post has clunky spots or mistakes, you might want to try looking at it hours or days later. These things may be fixed, plus valuable new material may have been added. My writing really tends to improve with seasoning.
I will, however, note if I have made a major change of opinion, or corrected an important mistake of fact that could be substantially harmful to a person or party. This is subject to interpretation, however. For example, if the post was up for two minutes before I fixed it, I may not write a correction note. Unless my blog traffic greatly increases, it's unlikely many people, or any people, saw it.
