I personally want "search by user name" reinstated. This community has what? 200,000 plus members? I can't believe that a decision was made based on the actions of a few. Instead of banning the offenders, a vital part of the search function was taken away from us, the members. To me that is not acceptable.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
