MB is a new piece of software (the first fully-functional version was released in Jan 2004). At the moment there are already over 500 registered users. I am really thankful for all the suggestions many of them have sent to me. But MB is still far from finished. So if you are testing the program, then please take some time to write to me what you think about MB. It is of particular importance to me as a developer that I get feedback, and will enable me to develop an even better DNA analysis program.
