Firstly, I DO wish this venture well.
However, you say think of the MK fans, but, realistically how many people is that? As a previous poster said, they weren't too well supported over 20 years ago, how many of those are still likely to be interested? Also, fans of other clubs, even defunct ones, don't tend to change allegiance. The best hope would be attracting a new generation of fans but as other clubs are finding out, how?
