Mike,
While it is unfortunate to lose members I am sure the other 300+ members here will have a more enjoyable experience. I remember when we started this site the conversations we had regarding members elswhere that always seemed to be the root of controversy. I believe we gave them plenty of 2nd chances so I won't lose a wink of sleep over their departure.
The rules changes are appropriate and hopfully we can all move on now and enjoy our time here.
