You can vote for personal priorities of the region's problems and possible solutions.
A glaring omission, in my opinion, is that no mention is made at all of encouraging employers to put workplaces near transit. We can vote to raise the gas tax, put future housing by train stations, etc, all we want--but until we start paying attention to making the work end of our commutes transit friendly, it's not going to do much good.
Still, it doesn't take long, so make yourself heard.
At least they give you the option to vote for a few good ideas that are currently "beyond the pale", making planning a regional effort, instead of leaving it in the hands of cities, which generally are controlled by NIBMY jerks.
