Over the last few months, I have developed a Polling Station which I have improved a bit further recently. If you log in and view your polling station, you will find the list of all polls you have already voted in, those you haven't, new polls recently created, etc. The URL is the same for all members as well as for anonymous, first time visitors: http://en.minguo.info/polling_station.
Although still a bit primitive, the polling station already provides some important features not found elsewhere. Members who visit the site only occasionally or even regularly will find it convenient to visit their own polling station to check the latest polls and the latest polling activities.
Of course, we shall continue develop and improve the polling station, so that it becomes the real hub and control panel for all members.
