Implementation of ET changes in a voluntary way

Different stuff has been suggested for competitive ET many times. There were always flamewars about major changes, sometimes admins introduced things people were against and it turned out to be good, sometimes much wanted changes weren't done. Mostly things went well and after some whining at first people got used to it and the world went on.

But there are still many people who wish for certain things, such as the pro mode and similar stuff.
